Steps to reproduce

Start gvim with a buffer of

vim9script
echo 'here'
finish

run

:source

Observe a screen full of here. ^C stops it.

Delete the echo line. Run :source again. Observe gvim hangs and must be killed.

Take out the finish and things work as expected

Expected behaviour

finish doesn't cause problems

Version of Vim

8.2.4602

Environment

ubuntu, gtk3

Logs and stack traces

No response

Hi,

The support for sourcing a Vim9 script (https://github.com/vim/vim/pull/9974) is not yet merged.
This problem will be addressed by that PR.

Oops, misunderstood/anxious, clearly want to get my hands on it. Apologies for the noise.

Then again the script,

echo 'here'
finish

also hangs vim. So not a vim9issue
