The first thing to do is to look for warnings in the compilation of
fblasmodule.c that might lead to int->intp problems.
I did not see anything significant in the build log you last sent, but I
might have missed something.
The next thing to do is to track down where the segfault is happening.
You could try running gdb
from scipy.linalg import fblas
gdb will catch the segfault and show you where it died.
As a last resort, I insert print statements to guide me where the code
is dying and carefully inspect that section of code.
