Comment(by jseabold):

 To confirm, calling schur with the same sort function doesn't segfault?

 What is A.dtype.char? If this is somehow different on this architecture,
 then I guess this could be it.

 But my inkling since it's only on one architecture, on windows, and with
 this compiler / LAPACK configuration (ie., not in MKL/MSVC) is that this
 is a LAPACK bug. What else would only show up on windows SSE3 only with a
 callback? The callback prototype signature is clearly correct since it
 works elsewhere. How difficult is it to update from LAPACK 3.1.1? I'm not
 really setup for this...
