I think it's the shared libraries in combination with MPI. We've had  
those issues before on AIX, where it turned out to be completely  
impossible to get shared libraries working with the vendor-provided  
MPI version.

Actually, if the --disable-shared option solves it, could you see what  
happens if you try to compile without MPI, but with shared libraries?

If that works, we might take a middle road and just disable shared  
libraries when MPI is used. In all other cases it should work great,  
and it reduces the installation size by an order of magnitude (and  
there's always an option to disable it, just in case).
