delta: 🐛 memory allocation of 7881122326526296064 bytes failed

Hi @osa1, I think this crash is being caused by something particular to your environment. It looks like it’s crashing while loading the syntax highlighting assets from disk. Delta borrows code from bat to do that. I wonder whether you might have something funny going on with your local bat syntax/theme definitions? Could you try

bat cache --clear

and/or moving ~/.cache/bat and ~/.config/bat out of the way temporarily.

Thanks everyone! I’ll close this now. My understanding is that

1. People installing via cargo hit a known bug in syntect (https://github.com/trishume/syntect/pull/403#issuecomment-1003940363)
2. The workaround is cargo install --force --locked git-delta

But please keep the discussion going or re-open if you are encountering this problem and that doesn’t describe it.

Confirmed that adding --locked to the install command (cargo install --force --locked git-delta) fixes the issue.
