I've done some further debugging: contrary to what gdb suggested, the
reason for the abort is the gcc_assert call in unwind-dw2.c
(uw_init_context_1):
code = uw_frame_state_for (context, &fs);
gcc_assert (code == _URC_NO_REASON);
Single-stepping at the assembler level, I find that code is
_URC_END_OF_STACK, i.e. _Unwind_Find_FDE () in uw_frame_state_for ()
returned NULL.
Since this code is such a maze, I'm hard pressed to further debug this, so
any guidance is appreciated.
Rainer
