Just to add a note to this: John Hunter and I just finished teaching a python workshop here in Boulder, and one attendee had a recurring all-out crash on WinXP. Eventually John was able to track it to a bad BLAS call, but the death was an 'illegal instruction'. We then noticed that this was on an older Pentium III laptop, and I'd be willing to bet that the problem is an ATLAS compiled with SSE2 support. The PIII chip only has plain SSE, not SSE2, and that's the kind of crash I've seen when accidentally running code compiled in my office machine (a P4) on my laptop (a similarly old PIII). It may very well be that it's OK to ship binaries with ATLAS, but just to build them without any fancy instruction support (no SSE, SSE2 or anything else of that kind, just plain x87 code).
