How about capturing the message buffer, which I'm assuming would
contain the lisp backtrace, into a file?
No, the Lisp stack trace is grabbed directly from the interpreter
stack, since few crashes occur after Lisp errors, at least we hope so.
In any case, opening files from crashing programs is somewhat
problematic. It is quite common for the program to crash again while
trying to shut down more or less sanely from an unrecoverable error.
This is just not a very useful thing to pursue in my opinion,
certainly not for me (I don't have the skills needed to think about
the internal state of a crashing program).
Or, of course, simply writing the backtrace to a file.

Alternatively, use the 'lbt' command defined in src/.gdbinit from gdb,
and capture it in the same way as the C stack trace.
