The fix was released in nano-8.0.  Thanks again for reporting.

Hrrmm...  Somehow nano-5.9 and later do not crash on my usual machine, but on another machine (with the same distro as you are using) all released versions of nano crash.  :/

However, commit b8ead3b5 ("linter: use a format string, to deflect format-string attacks") from a good two months ago has fixed the issue.  This fix will be in the next release.  Thanks for reporting.

Thanks for the file -- with it I can reproduce the crash when using nano-4.8.  And it crashes up to nano-5.8.  From version 5.9 onward, nano no longer crashes when invoking the linter (`gcc -fsyntax-only`) on this file.  Just by looking at the commits, though, I cannot figure out which commit fixed the issue.

Anyway, if you want a better nano on your older distro, I would suggest you build nano-7.2 from source.

To reword my response: I cannot reproduce the crash.  Can you reproduce it yourself?  If yes, then please post detailed reproduction steps.

For me to be able to reproduce this, you will need to provide the file that you run the linter on.  Because with 'extendsyntax c linter gcc -fsyntax-only' and introducing two syntax errors in src/cut.c and then running the linter on it, I can move through the messages (and try to go beyond first and last) just fine, without nano crashing.  Even when using nano-4.8.
