confirmed, reduced C tescase:
------------------------------------------------------------------------------
cblas_csyr2k (int N, void *A, int lda, float *B, int ldb, float *C, int k)
{
int i, j;
for (;; k ++)
{
for (i = 0; i < N; i ++)
{
float t = ((float * ) A) [i];
for (j = i; j < N; j ++)
{
C [i + j] = B [ldb] * ((float *) A) [k];
C [lda] = 0 ;
}
}
}
}
