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.

According to this:


it doesn't support GCC-produced DWARF2 debug info, unless you apply
patches both to Breakpad and to Binutils.
