I'm creating an app that's supposed to show some images on a Fragment, most of them downloaded from the internet.
I'm using Glide to handle that image loading for me on my CardViews and Fresco on my image slider (And this question on SO explains why I'm using two image libs).
The Fresco part of the lib is mostly based on this fork of the AndroidImageSlider.
Important: The images that I'm trying to load can either be PNG or SVG.
More info: I'm using a Moto Maxx (international version of the Droid Turbo) running Android 5.0.2. Also happened on a Samsung Galaxy S4 running Android 4.4.2 (cyanogen mod), but it happens a lot less often.
P.S.: I'm NOT using NDK.
Sometimes, my app just crashes, out of nowhere, and even without any user interaction. And when it does, I'm getting the following error message on the logcat:
Fatal signal 7 (SIGBUS), code 2, fault addr 0x9a74c060 in tid 21894

EDIT: Also happened on a Samsung Galaxy S4, tombstone can be found here.
Inside my CardAdapter, I'm loading the images like this (The SVG part was taken from here):
if (mod.getImg_type() == ImageTypes.SVG) {
GenericRequestBuilder<Uri, InputStream, SVG, PictureDrawable> requestBuilder;
SVGDecoder decoder = new SVGDecoder(PreserveAspectRatio.STRETCH);
requestBuilder = Glide.with(mContext)
.using(Glide.buildStreamModelLoader(Uri.class, mContext), InputStream.class)
.from(Uri.class)
.as(SVG.class)
.transcode(new SvgDrawableTranscoder(), PictureDrawable.class)
.sourceEncoder(new StreamEncoder())
.cacheDecoder(new FileToStreamDecoder<>(decoder))
.decoder(decoder)
.placeholder(R.drawable.modulo)
.error(R.drawable.banner_error)
.animate(android.R.anim.fade_in)
.listener(new SvgSoftwareLayerSetter<Uri>());
requestBuilder
.diskCacheStrategy(DiskCacheStrategy.SOURCE)
.load(Uri.parse(mod.getUrl_icon()))
.into(cardHolder.iv_card);
}
else {
Glide.with(mContext)
.load(mod.getUrl_icon())
.placeholder(R.drawable.modulo)
.error(R.drawable.banner_error)
.centerCrop()
.crossFade()
.into(cardHolder.iv_card);
}
And the XML file looks like this:

I've found a few questions here on SO, but none of them really helped with my problem. And it's a bit hard to reproduce it. Sometimes the app doesn't crash at all, even after 30 minutes on the faulty screen. On the other hand, it happened just after the images were shown.
Some questions I've found:
And many others...
And here's a screenshot from the app, taken from the bug report generated by my phone:
I have seen in some places that this problem might be related to low memory. But I think that's unlikely, since my phone got 3GB or RAM, and I'm loading fewer images comparing to the native gallery app (which is not crashing on my phone).
On the other hand, the thread on the skia issue tracker suggests it's related to the SVG lib.
Update: I've found this link on the Android issue tracker, and this one on the skia issue tracker, which is most likely related to the problem.
Other update: I've removed the slider, and the app stopped crashing. I guess the problem is in there.
Yet another update: I've changed the slider to load only PNG or only SVG in a given time. The app only crashed while loading the SVG images. So perhaps the problem is on the SVG lib.
Loading the SVG from a file also crashes.

I wouldn't really have a solution but I believe that I have some useful tips in order to help you digging further on the problem, but it was quite long for a comment
You already have narrow down the issue. The problem is most probably on some or all the SVG's.
So I would focus to identify if all the SVG's or some of them are causing that problem.
Navigating on the "SVG lib" code you mentioned it doesn't look that it has any native components, so I wouldn't blame it.
Checking your backtrace its quite clear that the crash is on "Skia" native library (libskia.so).
Posting bellow the human readable part of your backtrace:
/system/lib/libskia.so (S32_opaque_D32_nofilter_DX_neon(SkBitmapProcState const&, unsigned int const*, int, unsigned int*)+141)
/system/lib/libskia.so (SkBitmapProcShader::BitmapProcShaderContext::shadeSpan(int, int, unsigned int*, int)+86)
/system/lib/libskia.so (SkARGB32_Shader_Blitter::blitV(int, int, int, unsigned char)+528)
/system/lib/libskia.so (SkScan::AntiFillRect(SkRect const&, SkRegion const*, SkBlitter*)+178)
/system/lib/libskia.so (SkScan::AntiFillRect(SkRect const&, SkRasterClip const&, SkBlitter*)+14)
/system/lib/libskia.so (SkDraw::drawRect(SkRect const&, SkPaint const&) const+252)
/system/lib/libskia.so (SkDraw::drawBitmap(SkBitmap const&, SkMatrix const&, SkPaint const&) const+276)
/system/lib/libskia.so (SkCanvas::drawBitmap(SkBitmap const&, float, float, SkPaint const*)+116)
/system/lib/libskia.so (SkPicturePlayback::draw(SkCanvas&, SkDrawPictureCallback*)+1186)
Backtrace is read from top to bottom so the 1st line I posted is what exactly crashed. Some opaque thing without filter on something neon. (NEON is on the processor chip and either the device support it or not)
Some extra details about the Skia library:
Skia is an open source 2D graphics library which provides common APIs that work across a variety of hardware and software platforms. It serves as the graphics engine for Google Chrome and Chrome OS, Android, Mozilla Firefox and Firefox OS, and many other products.
Skia is sponsored and managed by Google, but is available for use by anyone under the BSD Free Software License. While engineering of the core components is done by the Skia development team, we consider contributions from any source.
So, the problem is most probably to the "Android Source Code" or the ROMs that your testing devices use. Have you tested the application on a vanila android to see if it still crashes? Or at least something that does not have some custom ROM as you may hit some limitation there. I have faced some limitations myself on custom ROMS regarding neon features but never on an OEM/Stock ROM.
Last but not least, there are some limitation when loading SVGs to Android, so another probability is to hit one of them. Googling arround I've found an article mentioning it, not sure if it the only one though.
The Android Developer reference recommends that a vector image be limited to a maximum of 200 x 200 dpi, as the initial loading of a vector graphic can be relatively expensive, leading to long draw times.
