The OpenBSD 6.0 release was announced slightly under 12 hours before Jeff
announced the Open MPI 2.0.1rc3 tarball.
So, I just *had* to try them out together.
First, let me say that I have no expectation that the following issue be
fixed for 2.0.1, but hopefully before 2.2.
It appears that abort() is being called from mprotect() when called from
the patcher code.
This is very likely to be because the call asks for RWX, but by default
OpenBSD-6.0 *prohibits* W+X.
To allow both Write and eXec requires *both* a linker flag
(-Wl,-z,wxneeded) and that the executable be on an f/s mounted with the
"wxallowed" option.
Manually working to satisfy those conditions allows "make check" and ring_c
to run w/o failures.
