[llvm-dev] Interesting puzzle for some openmp guru

[Johannes Doerfert via llvm-dev]

CC'ing the people that can probably tell you. My money is on the
interaction of the GNU/OpenMP compatibility layer in LLVM/OpenMP
and some calls getting resolved to the wrong place while others
go to "the right place".

I would assume simply telling gcc to use the LLVM/OpenMP runtime
might be enough here. Having two OpenMP runtimes used is probably
not a good idea even if it "works".
