I ran "python setup.py bdist_wheel" on numpy-1.11.2rc1 on Linux: no issue.
I compiled Python 3.6 (the default branch in fact, so the future 3.7) in debug
mode/64 bit with SSL, but the setup.py command failed with:
Don't know how to compile Fortran code on platform 'nt'
I don't want to spend too much time to try to reproduce the issue.
Can you please try to get the Python traceback? Try:
python -X faulthandler setup.py bdist_wheel
It seems like the crash occurs in parse_envlist(), function to parse
environment variables in os.spawnve(). Can you try to dump the env parameter of
os.spawnve()?
For example, you can put the following lines at the beginning of setup.py:
---
import os
orig_spawnve = os.spawnve
def log_spawnve(*args):
print("spawnve: %r" % (args,))
return orig_spawnve(*args)
os.spawnve = log_spawnve
---
My test:
---
>>> import os, sys; args=[sys.executable, "-c", "pass"]; os.spawnve(os.P_WAIT,
>>> args[0], args, None)
spawnve: (0, '/home/haypo/prog/python/default/python',
['/home/haypo/prog/python/default/python', '-c', 'pass'], None)
