<pre>When compiling with debugging symbols, GNU ld reports the file and line of the
reference. lld is missing this feature on MinGW. It works correctly on Linux.
$ cat test.cpp
void func();
int main(int argc, char **argv)
{
func();
return 0;
}
$ g++ -g test.cpp
C:\Users\orgads\AppData\Local\Temp\cci25Lpz.o: In function `main':
