Not sure it would help. A backtrace, even a full one, usually immediately raises questions that need a live GDB session and an end user ready to use it, to answer them. Without that, a backtrace is more often than not just a teaser. > We can't use MiniDumpWriteDump because gdb can't read Windows minidump > files, and windbg can't understand DWARF symbols.

According to this: https://code.google.com/p/google-breakpad/issues/detail?id=436 it doesn't support GCC-produced DWARF2 debug info, unless you apply patches both to Breakpad and to Binutils.
