https://issues.dlang.org/show_bug.cgi?id=18928 Issue ID: 18928 Summary: extern(C++) bad codegen, wrong calling convention Product: D Version: D2 Hardware: x86_64 OS: Windows Status: NEW Severity: critical Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: turkeyman gmail.com Created attachment 1698 --> https://issues.dlang.org/attachment.cgi?id=1698&action=edit Test app Crashing from bad codegen, uses wrong registers passing arguments. Test calls a static function and a virtual function. Static function works as expected, virtual call crashes. Open the project in VS2015 (others may work) and build + run. Place a breakpoint in the virtual `addUser`function and notice that it didn't receive its argument correctly, and also fails to return its result correct. Static version of the function calls properly. --
