If I try to multiply matrices greater than 51x51 elements the program breaks with the message: Here is the details of the installation sent to Debian bug tracker: The error occurs too in Octave 3.2.4 from the Debian GNU/kFreeBSD repositories This error does not occurs in Debian GNU/Linux with the same version of all libraries. Inspecting in detail, the source of the error is a matrix multiplication.įor matrices larger than 51x51 Octave crashes with a 'panic: Illegal instruction - stopping myself.' message. The compilation proccess terminates normally but in make check an error occurs checking the scripts/special-matrix/hadamard.m function. I've compiled the 3.4.0 version in my new Debian GNU/kFreeBSD installation. Here is a small example in C to check the behavior of ATLAS (modify the #define N line in order to see the results: with 51 runs but with 52 or more crash in Debian GNU/kFreeBSD):Ĭblas_dgemm(CblasColMajor,CblasNoTrans,CblasNoTrans,N,N,N,1.0,A,N,B,N,1.0,C,N) Ĭompiling order: gcc test.c -o test -lcblas I'll send a message in the ATLAS mailing lists.

I'm not a user of pure FreeBSD system so I don't know if the error is present there. But I don't know the reason for the correct behavior in Linux and incorrect in kFreeBSD. In Debian GNU/kFreeBSD repositories is provided the 3.8.3 version of ATLAS that is the same as in the Debian GNU/Linux repos. I can't check the 3.4.0 version because I have no time to recompile it with a reference BLAS, but if I install the Octave 3.2.4 from the Debian kFreeBSD repos and I use only the reference BLAS the error dissapears.
