[Numpy-discussion] Numpy 1.11.3, scipy 0.18.1, MSVC 2015 and crashes in complex functions

[David Cournapeau]

Indeed. I wrongly assumed that since gholke's wheels did not crash, they
did not run into that issue.

That sounds like an ABI issue, since I suspect intel math library supports
C99 complex numbers. I will add info on that issue then,
