<pre>G++ doesn't show such long paths, but clang++ does
It would be best if these could be converted to absolute paths immediately with
realpath() so that only absolute paths appeared in errors/warnings later in
output.
Observed:
/usr/bin/../lib/gcc/x86_64-linux-gnu/8/../../../../include/c++/8/bits/basic_string.h
Expected:
/usr/include/c++/8/bits/basic_string.h
Example program :-
#include <string>
int main()
{
std::string str("hello ");
std::size_t s = str.find(" ");
str.erase(s, str.end());
}
Current output from my clang 6, which appears similar to clang trunk on
godbolt.org
$ clang++ -Wall -o stl_string stl_string.cpp
stl_string.cpp:7:9: error: no matching member function for call to 'erase'
str.erase(s, str.end());
