Hi,
I'm workon on building manylinux wheels for numpy, and I ran into
unexpected problems with a numpy built against the ATLAS 3.8 binaries
supplied by CentOS 5.
I'm working on the manylinux docker container [1]
To get ATLAS, I'm doing `yum install atlas-devel` which gets the
default CentOS 5 ATLAS packages.
I then build numpy. Local tests work fine, but when I test on travis,
I get these errors [2]:
======================================================================

This is likely to
cause random crashes and wrong results. See numpy INSTALL.txt for more
information.
Sure enough, scipy built the same way segfaults or fails to import (see [2]).
I get no errors for an openblas build.
Does anyone recognize these? How should I modify the build to avoid them?
Cheers,
Matthew
