Description

The tests - tests/migration and tests/megampi fail when run on two processors on Stampede2 with the build mpi-linux-x86_64.

To reproduce:
1. Build AMPI: ./build AMPI mpi-linux-x86_64 -j10 -O0 -g
2. Request a development job : idev -t 00:30:00 -N 1 -n 2
3. Inside tests/ampi/migration, run ibrun ./pgm +p2 +vp4

Similarly for tests/ampi/megampi.

I couldn't get the stacktrace from the produced core dump as I'm getting warnings for missing debug-info (in spite of compiling with -g -O0).

These errors can be reproduced on the ofi build too.

You just need to add '+isomalloc_sync' on Stampede2 and it works on OFI and MPI, non-SMP and SMP. A warning is printed out when you don't use '+isomalloc_sync' so I am just marking this 'rejected'.
