This long-standing problem appears occasionally, and only disappears if you
kill the buffer completely, then reopen the file. I never got to report it
because I never could find steps to reproduce it… until now :) Nvm the
non-sense code, I reduced testcase as far as I managed.
# Steps to reproduce:
1. Save the following text in `test.cpp`
int main() {
puts(It's");
auto foo = []()-> void { };
puts("It's");
}
2. Open `emacs -Q ./test.cpp`
3. Now, the text lacks a quote in the first `puts(It's");`. Add it so it looks like
`puts("It's");`. Essentially, if you'd compile it with g++, it lacks any syntax
error besides `puts` being undeclared.
# Expected
The line with `auto foo…` is not red.
# Actual
The line with `auto foo…` (in particular) becomes red.
# Additional information
Emacs version GNU Emacs 27.0.50 (build 1, x86_64-pc-linux-gnu, GTK+ Version
3.22.30) of 2018-10-01, build with -flto.
