As a comment just below says, the solution is quite simple:

Here is the output with the environment variable set.

This doesn't provide anything useful either.

Seems like there's an architecture error or something, the last line indicates you might have an error with the flag:

> zsh: illegal hardware instruction LLVM_SYMBOLIZER_PATH=/usr/local/opt/llvm/bin/llvm-symbolizer swift main.swift

[alain_gilbert]

that's not related to the symbolizer thing. It seems to just be part of the "index out of range" crash. I get the same thing without using the symbolizer.

Ouch, and yuk. I stand corrected!
