Re: How to use core.atomic.cas with (function) pointers?

2019-01-22 Thread Kagamin via Digitalmars-d-learn
I believe this is historical. It will fail because atomics are combinatorially parameterized because the compiler couldn't properly infer template arguments until recently (this also resulted in memory corruption in ldc fork of druntime). Now that the compiler was fixed, atomics can be fixed to
