Android Fatal Signal 7 (SIGBUS)

Question

I'm getting a few SIGBUS (7) and SIGSEGV (11) crashes that I am having difficult tracking down.

The thread that appears to be causing the crash is primarily used for loading images to be displayed which makes sense since the logs indicate something failing with the SkJPEGImageDecoder.

I re-use memory for Bitmaps in accordance with this guide

Could it have something to do with that?

As per this document, it appears that SIGBUS 7 is a data misalignment issue, and SIGSEGV 11 is a write to inaccessible memory.

Answer 1

Your misalignment is at address 0x0000001e. That's a very peculiar address- it's almost certain to be wrong. Most likely you're passing in a null pointer somewhere and the C library is trying to either do an array access into it at 30 bytes in, or it thinks its a class and is trying to access some member variable 30 bytes in. Either way I'd put null checks around anything that could even remotely call into the image libraries, and put isRecycled checks around any bitmap objects to find where you're passing in bad values.
