Issue ID: 20579 Summary: TypeInfo.opEquals is broken Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: enhancement Priority: P1 Component: druntime Assignee: nob...@puremagic.com Reporter: rma...@gmail.com struct A(T) {} template B(T) { struct C {} } void main() { assert(typeid(A!(B!int.C)) != typeid(A!(B!string.C))); // assertion failure! } This fails on all platforms. The problem is the attempted fix for TypeInfo.opEquals for DLLs falls back to comparing non-unique strings like TypeInfo_Struct.name. This doesn't help anyway since casting is broken for Windows DLLs, so it just breaks things by creating false-positives in other cases. --
