I can reproduce the issue on 10.6, where I used to be able to build
numpy/scipy before with the exact same configuration (10.6, gfortran from
ATT, official gcc-4.2 compilers from Apple).

I reduced the issue to be related to 32 bits only, and when built against
numpy 1.9.1. I don't have the issue when building scipy against 1.8.1.

This suggests some incompatibilities in compilation options that have
changed in numpy between 1.8.1 and 1.9.1.

P.S: one should not use -ff2c flags.
