[Rivet] Segmentation Fault when running Rivet 2.5.0

[Christian Johnson]

Hi Chris and Andy,

Thanks for the info! 

So through some more testing, I found that I was not properly linking gcc to begin with so Rivet was building against clang.
So I think the issue it with clang.

I verified this by uninstalling everything in Homebrew to start clean and then used the rivet-bootstrap to install everything.
I am still running into the same error as before. Let me try running the RIVETDEV option.

Cheers,
Christian
