I did a clean installation, the compiler is gcc 4.8.1, let me know if you need
any additional info.
Any hints would be appreciated.
The code in question has a bug, though it is entirely bizarre that without the
= sign between ierr and MPI_Allgather, it actually compiles for me. It must
have something strange to do with what MPI_Allgather probably expands to.
The patch is here:
https://github.com/dealii/dealii/pull/3598
I'm going to take the (unusual) liberty to approve it myself, so it should be
fixed if you update your git version.
Best
W.
