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.

Right.

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.
