I've seen advice that suggests that if you want to compile using GCC on a mac you need to install gcc the following way, without multilib.
brew install homebrew/versions/gcc6 --without-multilib
Here's an example question to that point.
What does gcc without multilib mean?
Recently I forgot to follow this advice and just did (I think):
brew install gcc
This installed much quicker and seem to be working fine. Rereading about the without-multilib option, I seem to remember seeing that this may have been a bug in older versions of GCC.
So my question is, is there any reason why one might prefer the without-multilib option for openmp on a mac, besides file size?
