Btw, I tried to debug it using:

$ winedbg --gdb "C:\Python27\python"

and I got:


Wine-gdb> backtrace
#0  0x7bc73735 in call_exception_handler ()
   from /usr/bin/../lib32/wine/ntdll.dll.so
#1  0x7bc76397 in ?? () from /usr/bin/../lib32/wine/ntdll.dll.so
#2  0xdeadbabe in ?? ()
Backtrace stopped: Not enough registers or memory available to unwind further



So unfortunately it doesn't show where exactly it fails, I would need
to get the full stack trace. Also I noticed even simpler
way to segfault it:

import numpy
numpy.array([1j])
