https://issues.dlang.org/show_bug.cgi?id=15193 Issue ID: 15193 Summary: DIP25 (implementation): Lifetimes of temporaries tracked incorrectly Product: D Version: D2 Hardware: All OS: All Status: NEW Severity: normal Priority: P1 Component: dmd Assignee: nobody puremagic.com Reporter: timon.gehr gmx.ch The following code corrupts memory. enum N=100; ref int[N] foo() safe{ struct S{ int[N] x; ref int[N] bar()return{ return x; } } return S().bar(); } ref int[N] baz() safe{ return foo(); } void bang(ref int[N] x) safe{ x[]=0x25BAD; } void main() safe{ bang(baz()); } (Contrast this with: ref int foo() safe{ struct S{ int x; ref int bar()return{ return x; } } S s; return s.bar(); } This is rejected correctly.) --
