CC Mode 5.35.1 (C++//l); C++11 string literal operator mishighlighted |
|

Package: cc-mode
Hi Alan,
The code below (which is valid since C++11) is mishighlighted,
with the open-paren after "_opcode" in font-lock-warning face
and the subsequent characters in font-lock-string-face. This is
unstable: inserting and deleting a character before the open-
paren fixes the highlighting, and [M-x normal-mode RET] breaks
it again.

#include <cstddef>
int operator""_opcode(const char *p, std::size_t size) {
return 0;
}

Thanks for the quick response! I've committed the fix to CC Mode and
the Emacs master branch at savannah, and I'm closing the bug with this
post.
