New description:
This problem started with GCC12, and continues with GCC13. Also, GCC14 -
but that one simply doesn't work, so better to concentrate on releases
that otherwise do compile successfully.
File in question {{{t3.cpp}}}:
{{{
#include <iostream>
int main() {
std::cout << "Hello World!" << std::endl;
return 0;
}
}}}
"Normal" compilation:
{{{
$ g++-mp-13 -pipe -o t3 t3.cpp
$ ./t3
Hello World!
$
}}}
Attempt to compile with {{{-libstd=libc++}}}:
{{{
$ g++-mp-13 -pipe -stdlib=libc++ -o t3 t3.cpp
