Hmm. Because the other way this could be addressed is
to fix gdb. (1) it shouldn't crash and (2) it could
support elf alongside pe-coff fairly easily i'd imagine;
just a matter of enabling that bfd backend.
Shall we ask gdb maintainers?

Fixing problems at their source - in this
case fixing gdb - is of course the best solution.
For the w64 port of gdb, I needed a quick solution.
Usually it will take some time to ask the gdb maintainers,
find a solution, get distributions which include the solution
and use such distributions everywhere.
I don't think that the setup with pe-coff (when it is supported)
will be 100 % identical to the elf setup, so most probably we'll
need a test for ELF / not ELF anyway.
Therefore I suggest to apply my patch, even it is only an
intermediate solution for the next year.

Stefan W.

Could you file a gdb bug report?
