Issue #10008 has been updated by Jared Beck.


> Which conftest?

I think conftest is defined in the `configure` script.  For me, it's around line 20376, which looks like:

    cat confdefs.h - <<_ACEOF >conftest.$ac_ext

Furthermore, line 20389 defines a `sigsegv` function.

    void sigsegv(int signum, siginfo_t *info, void *ctx){

This `sigsegv` function can be seen on line 3 of the "Dispatch queue" from the crash dump:

    Thread 0 Crashed:: Dispatch queue: com.apple.main-thread
    0 libsystem_kernel.dylib 0x00007fff8b3f7866 __pthread_kill + 10
    1 libsystem_pthread.dylib 0x00007fff8f8df35c pthread_kill + 92
    2 libsystem_c.dylib 0x00007fff9000ab1a abort + 125
    3 conftest 0x000000010c2dee55 sigsegv + 37
    4 libsystem_platform.dylib 0x00007fff8cfdd5aa _sigtramp + 26
    5 ??? 000000000000000000 0 + 0
    6 libdyld.dylib 0x00007fff8efa35fd start + 1

Finally, it may be relevant that my `./configure` output reports "broken backtrace":

    checking for broken backtrace... yes

I hope that helps!
