For this precise combination, it's non-existing, but the principle still
holds.

What second crash? I only see one gdb session. There is first a SIGTRAP,
which is used by gdb for its own debugging purpose, then a SIGABRT. The
second signal is very probably just a consequence of bad interaction
between the program and gdb on the SIGTRAP. Thus why rather working on a
core file.
