Note, your FormInitialGuess does not initialize bb[0] and bb[1].

This should be sent to the MUMPS list. So far we did not see a way to tell
them
about the integer type. They might say they rely on Fortran to do it, but
we can't
since that is unreliable from configure.

Hello,
I am getting an "INFOG(1) = -51 integer overflow" error from Mumps
because the linear system I am solving is very big. I have tried to
configure Mumps in a full 64-bit integer version using
===
./configure --with-64-bit-indices --with-cc=gcc
