Segmentation Fault using cblas_sgemm

[liumil...@gmail.com]

In my multiple-thread code,I just call cblas_sgemm fucntion to calculate the output value.When it will core dump sometimes,It report 0x000000000065049f in sgemm_incopy.How can I solve it this issue?Is it thread-safe this function.I am afraid there is some bug using in multiple thread.Who has met the same issue?

How does you build the library?

I think I fixed this bug.I read the issues yesterday.Now I build it with USE_THREAD=0.And no cores.But I still has one question,is it slower when call cblas_sgemm function if build with USE_THREAD=0?

And it is correct when I build it with USE_THREAD using in multiple-thread code,isn't is ?
