https://issues.dlang.org/show_bug.cgi?id=20809 Issue ID: 20809 Summary: return statement might access memory from destructed temporary Product: D Version: D2 Hardware: x86_64 OS: Linux Status: NEW Severity: regression Priority: P1 Component: dmd Assignee: nobody@puremagic.com Reporter: dlang@foerdi.net Hi, See this reduced code: https://run.dlang.io/is/yoyHXC I would expect that foo() returns 2. My guess in foo is: The return value of val is saved locally as a ref int and then the destructor of S is called (the local cache is pointing to 0). Now the ref value is dereferenced and returned. The last working version of dmd was 2.089 Maybe this issue is related to https://issues.dlang.org/show_bug.cgi?id=14696 (?) - foerdi -- |
