Bug#613094: libatlas: Error in cblas_dgemm in ATLAS 3.8.3 in Debian GNU/kFreeBSD 32 bits

[José Luis García Pallero]

Package: libatlas3gf-base
Version: 3.8.3-29
Severity: grave
File: libatlas
Justification: renders package unusable


In Debian GNU/Linux all runs OK, but in the new Debian GNU/kFreeBSD an error with cblas_dgemm occurs (I don't know if the error
affects to sgemm, cgemm and/or zgemm). If I try to multiply two matrices bigger than 51x51 elements ATLAS crashes with an
"Illegal instruction" message. Here is a simple program to demonstrate the fact:

#include<cblas.h>
#define N 52
int main()
{
   double A[N*N],B[N*N],C[N*N];
   cblas_dgemm(CblasColMajor,CblasNoTrans,CblasNoTrans,N,N,N,1.0,A,N,B,N,1.0,C,N);
   return 0;
}

I don't know if the error persists in the current ATLAS development sources and/or in pure FreeBSD systems.
