https://issues.dlang.org/show_bug.cgi?id=20359 Issue ID: 20359 Summary: core.atomic.cas throws with null as `ifThis` Product: D Version: D2 Hardware: x86_64 OS: Windows Status: NEW Severity: normal Priority: P1 Component: druntime Assignee: nobody puremagic.com Reporter: johnch_atms hotmail.com The following code produces an access violation in the 2.089.0 release: import core.atomic; void main() { Object a, b = new Object; cas(&a, null, b); } If you cast everything to shared - cas(cast(shared)&a, cast(shared)null, cast(shared)b) - it works as expected. Also if you pass an instantiated object to the `ifThis` argument, it will also work correctly. --
