panic detected when use moar for git diff

[haunt98]

I use git diff -w with moar config in ~/.zshrc

# https://github.com/walles/moar
if command -v moar &>/dev/null; then
    export MOAR="-no-linenumbers -no-statusbar -quit-if-one-screen -wrap"
    export PAGER=moar
fi

Dowgrade to v1.23.5 work fine

[dsully]

Seeing the same thing.

[walles]

Confirmed.

Workarounds for now is to either downgrade (as you did) or drop -quit-if-one-screen.

[walles]

Fixed in v1.24.2, just made a new release: https://github.com/walles/moar/releases/tag/v1.24.2

[haunt98]

Thank @walles for your fast response! Thank for the good tool again!

[dsully]

Unfortunately that didn't work for me.
