28.0.50; C code not being correctly fontified in features/native-comp |
|
Date: |
Thu, 29 Apr 2021 11:14:44 +0100 |
This happens with a lot of C files but for a concrete reproducible
example from my development repository:
https://github.com/stsquad/qemu/blob/review/qtest-accel-check-v4/tests/qtest/arm-cpu-features.c
Running:
emacs -Q tests/qtest/arm-cpu-features.c
And witness the lack of fontification from half way through assert_error
although resp_has_props seems to recover for the function prototype and
initial variable. When I run:
M-x font-lock-debug-fontify
The fontification fixes itself although I get a bunch of errors in

OK, after recompiling the CC mode files, the problem is indeed gone.
Closing.
