Issue ID: 20809
Summary: return statement might access memory from destructed
temporary
Product: D
Version: D2
Hardware: x86_64

Status: NEW
Severity: regression
Priority: P1

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
