@pavanky Is this a cgemm only issue? When merging PR #199 I built the code with python 2.7 on hawaii and fiji on both windows and linux and did not see any test fails.

@TimmyLiu ~~This is only a~~ We have only noticed the problem with cgemm and zgemm.

@pavanky can we close this issue with pr #202 being merged?
