On a PPC64 host with gcc-4.8.3 I have configured with
--prefix=[...] --enable-debug \
CFLAGS=-m64 --with-wrapper-cflags=-m64 \
CXXFLAGS=-m64 --with-wrapper-cxxflags=-m64 \
FCFLAGS=-m64 --with-wrapper-fcflags=-m64
I see "make check" report a failure from opal_fifo.
Previous testing of Open MPI 2.1.1rc1 did not fail this test.
I also noticed the following warnings from building opal_lifo and opal_fifo
tests, but have found that adding the volatile qualifier in opal_fifo.c did
*not* resolve the failure.
