I bet you are running out of memory at this point and that this is the
cause of the internal compiler error. Try again with 'make -j1'.

Hm, good question. What happens if you say
/usr/local/mpi3/bin/mpicxx -v
and
gcc -v
? Are they the same compiler version?

My best guess is that there is a disconnect between two compilers
installed on your system.
An alternative would be for you to use the current development version
(which is actually quite stable). If you want to try that out, just
clone the github repository onto your hard drive and go through the same
configuration steps you do above.
