Thanks, Robert.
Can you do
numpy.test(verbosity=2)
OK. Here is the line that fails: check_matvec (numpy.core.tests.test_numeric.TestDot)Floating exception (core dumped)
A gdb backtrace would also help.
OK. I'm pretty ignorant about using debuggers, but I did "gdb python core.23696" and got the following. Does that help?
