Suggestions
- Check with different versions of ATLAS and Lapack.
- Run the program under valgrind, with python-specific suppressions
enabled. Python's source distribution has a suppression file for
Valgrind.
- Run the program in gdb, first having compiled everything with debug
symbols. (OPT="-ggdb" FOPT="-ggdb" python setup.py build ...)
Check if the values passed down to the LAPACK routine are OK.
Unfortunately, these take some work.
