As result, GDB says something like gdb: unknown target exception 0xc0000029 at 0x7c9502cc Would it make sense to report this as SIGSEGV instead? This happens, e.g., when a thread tries to longjmp using stack information recorded by a different thread. What will GDB report in such a case on GNU/Linux or other Posix platforms?
