4.5 isn't that new - nearly 2 years. 4.6 has been out for about a year
now, and 4.7 was just released. I've tested successfully on both
pretty regularly.

Another possible fix, based on the failure you saw, is to build
Charm++ with -D_FORTIFY_SOURCE=0, like so:

./build charm++ net-linux-x86_64 ibverbs --with-production -D_FORTIFY_SOURCE=0

If this helps, we should probably add it directly to Charm++'s build
flags, since we're unlikely to ever want Fortify enabled.
