I don't get to that point... I am not even able to use the wrapper
compilers (f.e. mpif90) to obtain an executable to run. The
segmentation fault happens when Open MPI utilities are being run, even

As I wrote in my previous e-mail, I tried configuring with and without
the MX libs, but this made no difference. It's only when I disabled
the memory manager, while still enabling MX, that I was able to get a
working build.
