panic with `%<number> is fixed`

Hi,

Unsure if this belongs here or should be reported at the erlang repo. Running pylyzer on a python script I'm working on always panics during the checking phase.

Log for running standalone:

Log when run inside neovim:

Under neovim I've seen a few different numbers being reported in the panic message, running standalone always gives the same number.

Thank you for your time.
