Package: vim-nox
Version: 2:9.1.2103-1
Severity: normal
X-Debbugs-Cc: [email protected]
I observe a bug with the following setup:
docker run --rm -ti debian:testing
apt update
apt install vim-nox
echo
N=2140324650240744961264423072839333563008614715144755017797754920881418023447140136643345519095804679610992851872470914587687396261921557363047454770520805119056493106681
> a.py
vim --clean a.py
The outcome is that vim errors out with:
E363: Pattern uses more memory than 'maxmempattern'
As a consequence of that error, syntax highlighting is then no longer
active in the buffer.
The precise vim version is:
vim --version | head -n 2

Upsteam has a strinkingly similar issue reported.

Apparently the collection of patches 1-2050 does not encounter the
issue, so the faulty patch might be in the set 949, 2051-2103
