https://issues.dlang.org/show_bug.cgi?id=21290 Issue ID: 21290 Summary: [REG2.092] Incorrect escape deprecation on scope lazy pointer parameter Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: regression Priority: P1 Component: dmd Assignee: nobody@puremagic.com Reporter: johanengelen@weka.io Test code: ``` void foo(scope lazy void* p); struct S { this(int a) { foo(&this); // line 5 } } ``` When compiled with dlang >= 2.092, the following deprecation message is shown: <source>(5): Deprecation: escaping reference to outer local variable `this` The deprecation message is incorrect because of `scope` in the function parameter signature. The code compiles without deprecation message when `lazy` is removed. (This is probably because DIP25 violations now show deprecation messages, i.e. DIP25 implementation bugs now start to surface. Deprecation message bugs are as bad as error bugs, because -de is used in settings where one does not want to disable it.) -- |
