Segfault while reading 2D GMSH file in parallel ?

[thelfer]

Hi all,
With the current master (built today), the following test crashes. It only tries to read a simple mesh in parallel. Sequential read is fine.
Before opening an issue, I would like to know if other people are able to reproduce this issue.

TestMesh.zip

$ cd TestMesh
$ mkdir build
$ cmake ../ -DCMAKE_BUILD_TYPE=Release -DMFEM_DIR=$MFEM_ROOT/lib/cmake/mfem/
$ make
$ cp ../mesh.msh .
$ ./test-mesh

where MFEM_ROOT contains to the path to the root of my MFEM installation

On my machine, I got the following output:

*** Process received signal ***
