One of these changes should be enough (you shouldn't need to do both). What's your Xcode version? Are you able to build 1.7.9-jumbo-5 (not -6) with OpenMP support on this same system and in this same way (without a workaround) just fine? If so, that's puzzling. These may be relevant: http://comments.gmane.org/gmane.comp.compilers.llvm.devel/37989 http://llvm.org/bugs/show_bug.cgi?id=4380 Eric - I thought you could want to comment on this, such as on whether this is in fact an instance of the same problem as mentioned at the URLs above or not and whether it is normal/expected that we're running into it on OS X 10.7.4 (you fixed the LLVM bug in 2010?) Thanks, Alexander
