I have. I have written a recipe for a package (namely yuzu emulator),
which depends on GCC 12. And it was actually an issue, I had to wrap
qtbase with a wrapper that goes over this problem.

It was actually fixed in later versions of qtbase-5, but I'm not sure
how this exactly works and if they are elegible for use in Guix.

I don't know, it is a hidden bug that is likely to cause quite a big
problem once Guix moves to GCC 11 or later, as many apps probably won't update to
Qt 6.

Kind regards,
