Segfault with openblas 0.3.10 #104

Closed ogrisel closed 4 years ago

ogrisel commented 4 years ago

I have observed a regression with openblas 0.3.10:

import numpy as np

np.ones(shape=(300000, 5)) @ np.ones(shape=(5, 5))

=> segfaults.

No problem with 0.3.9.

I will report upstream but maybe we might want to mark 0.3.10 as a bad release in conda-forge? Are we might do that once a bugfix release is available from upstream?

Original bug in scikit-learn: https://github.com/scikit-learn/scikit-learn/issues/17980

Hello @ogrisel, what platform / OS are you on?

This issue is very likely a duplicate of #101; we have already backported the upstream fix that's (in all likelihood) the underlying issue for this since yesterday, so could you please try updating to the latest build (openblas-0.3.10-<...>_4) and checking if the issue persists?

Sorry: Linux 64bit. Let me check.

ogrisel commented 4 years ago

I confirm your fix works. That was quick!

Thanks.
