Let's get this thread back to the errors. The problems seem specific to the python.org amd64 python, is that correct?
No, the unofficial scipy-0.8.0rc1.win32-py2.6 build fails with (mostly) the same errors. Most of the reported errors are apparently specific to my build environment: msvc9, ifort 11.1, mkl 10.2, numscons 0.12.0dev.
The SuperLU failures puzzle me. It should be "straightforward" C code, and I don't understand what can go wrong there. The "Factor is exactly singular" error indicates essentially means that SuperLU thinks it detects a zero pivot or something, so something seems to fail at a fairly low level.
This seems quite difficult to debug without a Win-64 at hand.
Another thing is that Gohlke's binaries are also built against MKL, and SuperLU does call BLAS routines. I wonder if something can break because of that...
@Robin: Also, for the cases where a wrong result is produced with no error: is it easy to write a small test program demonstrating this? If yes, could you write one?
