well, maybe not completely worthless: the segfault happens in the arctan
function, presumably because the compiler links a wrong set of mathematical
libraries. There is something weird in the software of your machine.

QE does not use any nonstandard, "advanced", exotic features of MPI, as far
as I know, All MPI libraries should work.
