Errors with the ./gen-git-build.sh

When I first ran ./gen-git-build.sh on macos Ventura 13.1, I got this error

$ ./gen-git-build.sh

Thank you for trying Mosh. I was able to reproduce this but no clue what's happening there. This is probably GC issue. Could you try GC_DONT_GC=1 ./gen-git-build.sh instead of ./gen-git-build.sh?

I did try it with and here's the error output

macOS have incompatible version of bison so you'll have to set PATH to Homebrew(or whatever) provided bison e.g.) export PATH=/usr/local/opt/bison/bin:$PATH

[bentxt]

thanks your solution worked:

brew install bison
export PATH=/usr/local/opt/bison/bin:$PATH
GC_DONT_GC=1 ./gen-git-build.sh
