version : ***** VIC Version 4.2.b+feature/glacier 2015-Feb-15 *****

compiler: gcc or clang

OS: macOS Big Sur 11.2.3

I am trying to compile and run VIC 4.2 on a macOS. The model compiles with a few warnings, but no errors. When running the model the following error is encountered.

...
Using 15 Snow Bands
Using 3 Root Zones
Model state will be saved on = 31/12/2011

Model output is in standard ASCII format.
zsh: illegal hardware instruction  ./src/vicNl -g global.params

I have tried compiling with gcc and clang, using different versions of VIC 4.2 and different (older) macOS versions. Any thoughts on what this error means?
