Nobody on this list is going to give you legal advice, but I will say
that the exception would be useless if you couldn't use std::string in
your own classes, so I consider this a rather silly question.

As the rationale at
https://www.gnu.org/licenses/gcc-exception-3.1-faq.html says:

As long as you use an Eligible Compilation Process, then you have
permission to take the Target Code that GCC generates and propagate it
“under terms of your choice.”
