--- Comment #4 from Moritz Baumann <moritz.baumann at sap dot com> ---
Raw string literals are still not handled correctly in macros in some cases:
#define myMacro(string) u##string
int square(int num) {
auto string = myMacro(R"EOF(
)EOF");
// intentional syntax error
return num * num
}
(https://godbolt.org/z/qYfax5E8x)
The line number in the compiler error message refers to a line that doesn't
even exist. It seems like line breaks in the raw string literal are counted
twice.
