Thanks for all your ideas. The next version will contain an augumented libopenblas.dll in both numpy and scipy. On the long term I would prefer an external openblas wheel package, if there is an agreement about this among numpy-dev.
Another idea for the future is to conditionally load a debug version of libopenblas instead. Together with the backtrace.dll (part of mingwstatic, but undocumentated right now) a meaningfull stacktrace in case of segfaults inside the code comiled with mingwstatic will be given.2015-01-26 2:16 GMT+01:00 Sturla Molden <sturla.molden@gmail.com>:On 25/01/15 22:15, Matthew Brett wrote:

Yes. Make something that works first, optimize for space later.

That is a good idea and we should do this for NumPy too I think.
