Any suggestions? If this issue is better suited for the Julia's main repo, please let me know.

Oooh, this looks like an interesting one. Looks like a possible LLVM error. We're probably going to have to build it outside of Homebrew to figure out what's going on. Sorry about that.

The reason why this is necessary is because we're going to have to modify Julia's source code a little bit to enable further debugging information. Please follow the instructions on the Julia website to clone the latest git revision to a local folder, and attempt to build Julia. To speed up your compilation, you can try adding on the USE_SYSTEM_XYZ stuff that Homebrew added on:

$ make USECLANG=1 USE_SYSTEM_ZLIB=1 USE_SYSTEM_FFTW=1 USE_SYSTEM_GLPK=1 USE_SYSTEM_GMP=1 USE_SYSTEM_LLVM=1 USE_SYSTEM_PCRE=1  USE_SYSTEM_MPFR=1

That should cover the majority of the time-consuming dependencies other than SuiteSparse and OpenBLAS, so compilation should only take a few minutes. If that fails, (which I hope it does, as that means it's a problem with Julia and not Homebrew!) please run the above make incantation, but append debug at the end, so we make the debug target. Then, get the gdb backtrace as described in this document in the "Segfaults during bootstrap" section. Post that information here, and we'll see what we can do.

Julia has changed quite a bit since you last posted this. If you're still interested in trying this out, please try again and open a new issue if youstill have problems.

I've since moved on to Linux on my laptop. If I run into issues on the Mac again, I'll definitely reopen this.
