d2: not getting any backtrace info

Question

I'm playing with the gtkd wrapper generator, and running into an std.conv exception for which I cannot manage to get any symbolic debug info at all. I've compiled with debug symbols:

$ dmd -gc -debug utils/HTODConvert.d utils/WrapperIF.d utils/funct.d utils/DefReader.d utils/GtkWrapper.d utils/HtmlStrip.d utils/IndentedStringBuilder.d utils/convparms.d utils/GtkDClass.d -ofgtkwrap 

but the backtrace is just a list of memory addresses:

std.conv.ConvException@/usr/include/d/std/conv.d(1779): Unexpected ' ' when converting from type string to type int

Make sure that your dmd.conf has -L--export-dynamic in its DFLAGS. I believe that the version provided with dmd has it, but without that, you won't get the function names, so there's a good chance that it's missing from your dmd.conf.
