That the problem would be in Python is not so clear to me. Can you try
running it with the previous Python shipped by Fedora? Do you see the
problem then? What's the previous version, btw?
Memory errors are somewhat difficult to debug. Can you try running only
a certain subset of the tests, first
Be sure to set Pythonpath so that you get the correct Numpy version. If
it segfaults, proceed to (under numpy/core/tests)
Since the crash occurs in cyclic garbage collection, I'm doubting a bit
the numpy/core/src/multiarray/numpymemoryview.c implementation, since
that's the only part in Numpy that supports that.
Alternatively, just replace numpymemoryview.c with the attached one
which has cyclic GC stripped, and see if you still get the crash.
