It's possible that the latter is a gtest issue instead; that specific failing
test was previously the source of a FTBFS on Hurd, though for a different
reason. I can't easily account for why it would only fail with OpenMPI but not
MPICH or the basic non-MPI build, though.
However, I think it's a low-importance test in this case - the build doesn't
use GPU support - so I may throw in another conditional to disable the test on
x32, with a note to revisit the issue the next time the gtest code is updated.
The thread safety warning is on all architectures, but if you still have a
build tree hanging around, could you please check that set of tests with this
command to be sure it's a non-issue?
Probably no difference, but it's fast. Thanks much for the testing help.
