ref_impl.text.cpp compilation fails g++-15 #91
Description
This seems to be something new with g++-15 as the current code compiles and runs with g++-14. This is on ubuntu arm64.
I haven't had time to dig into the compiler complaint here, but I'm going to assume it's reporting a real attempt to strip const from void*.
