Hi,

results:
>Out of curiosity, could you try this:

$ ./python -c "import faulthandler; faulthandler.enable(); faulthandler._stack_overflow()"; echo $?
zsh: illegal hardware instruction (core dumped)  ./python -c 
132

>And if you're motivated, you could try it again after having built python with './configure --without-threads'.

It does not build completely, I have a problem if I add --without-threads:
$ make
[...]
./Modules/posixmodule.c:4582: undefined reference to `sched_get_priority_min'
libpython3.3m.a(posixmodule.o)(.text+0x430b): In function `posix_sched_get_priority_max':
./Modules/posixmodule.c:4565: undefined reference to `sched_get_priority_max'
collect2: ld returned 1 exit status
*** Error code 1

It seems that it needs -pthread even if I precise --without-threads. Must I open a new ticket for this problem?

Thanks for your help,

Remi.
