Re: [OpenBLAS] OpenBLAS 0.1.0 stable version released

[Xianyi Zhang]

Hi Nitzan,

Thank you for you feedback!

The netlib refblas is written by Fortran. I think it's sequential, stable and correct. 

Thus,  it wasn't a BLAS bug to cause the crash.

It seems that this version improves the stability for "older pentiums".

I am still having a crash on an older core duo E6420 pentium, when opening
multiple fltk figures, however this is not dependent on specific libblas
(happens on Tatsuro's refblas and ATLAS based libblas as well). I suspect it
might be because of the graphics driver on that machine but I can't prove
it.

Thanks for this effort.

and test.
