The real solution is, unfortunately, quite a bit of work. In the meantime, we should probably annotate the shared variables and consider them volatile. This should prevent most optimizers from messing things up inadvertently. This should be done within OMP regions. Orphaned functions may become a problem, so this should be implemented as an IPA pass. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=31862
