Offtop, but I imagine this kind of an issue could also arise with a cuda application, and I wonder if you here might be the right people to ask: there's a program that is built with the gcc10StdenvCompat. It links dynamically against gcc10's libstdc++. At runtime the program needs to use opengl libraries (from the same nixpkgs revision), some of which link against gcc11's libstdc++. This results in a failure

I simply don't know what is the right way to deploy something like this (or if there is one) and it's kind of making me sad.
