I am testing a tarball built from v2.x-dev-1410-g81e0924
This includes pull request #1128 in which Nathan addressed multiple
"patcher" issues.
However, I see the crash below in dlopen_test on a LITTLE-ENDIAN Power8
system.
This is happening when built with "V13.1.2 (5725-C73, 5765-J08)", but not
with gcc on the same system.
So, I cannot conclusively assign blame to OpenMPI.
