The segfaults are because we forgot to increment the ABI version.
There's a thread about this on the Numpy list.

Scipy 0.8 will not be compatible with Numpy 1.2.x, and so the trunk will 
not build with Numpy 1.2.x.

If you want to test your backports to 0.7.x, I think you should anyway 
compile the 0.7.x branch, to which you are backporting the fixes, not the 
trunk from which you backport them.
