OK. I reproduce the problem and found I just now "succeeded" because I changed
mesh type to SerialMesh in my code and forgot to change it back.
If I use ParallelMesh and remove the is_serial() test in mesh_base.C, the code
ran into segfault with libmesh_opt.so and the following assertion
with libmesh_dbg.so
Assertion `incoming_header == node_magic_header' failed.
incoming_header = 96
node_magic_header = 1234567890
[0] src/parallel/parallel_node.C, line 194
It seems the conclusion is Parallel Mesh repartitioning is not ready in
libmesh?
Correct.
On the other hand, the problem that's being triggered there is in code
I think I still remember pretty well. I'll take a crack at
reproducing it tonight.
