Package: openblas
Version: 0.1.1-6
Severity: important
Tags: fixed-upstream

openblas crashes when used on a 32 bit athlon cpu.
This is caused by the dynamic parameters not being initialized for this cpu.
This means dgemm_p size is zero, when starting up the openblas it
benchmarks some memory. There it uses the zero dgemm size
(driver/others/memory.c:427) for allocation.
Allocation of size zero returns NULL and results in a crash.

see the upstream bug for a patch.
