Comment:
I've done some more extensive testing for this. Some observations:
- With sort=None, everything is fine. I tried testing with 1000s of
matrices of random numbers, with sizes from 2x2 to >1e3x1e3.
- With other sort functions segfaults occur as described above. Also for
the 4 sort functions that can be specified by a string.
- I double checked again the LWORK size, that seems correct. I hardcoded
larger sizes; independent of the size of LWORK segfaults occur.
The failures reported for rc2 on other platforms were due to a simple
unrelated issue, see PR-292. So it's still Windows only with ATLAS
binaries from the numpy vendor branch and SSE2/SSE3.
