Bug ID: 281
Summary: NRVO tests behave different than in DMD
Product: GDC
Version: development
Hardware: All
OS: All
Status: NEW
Severity: minor
Priority: Normal
Component: gdc
Assignee: ibuc...@gdcproject.org
Reporter: be...@caraus.de
extern (C) int printf(const(char*) fmt, ...);
/**********************************/
// 13089
struct S13089
{
@disable this(this); // non nothrow
}
void* p13089;
S13089[1000] foo13089() nothrow
{
typeof(return) data;
p13089 = &data;
return data;
}
void main()
{
immutable data = foo13089();
assert(p13089 == &data);
}
The assertion holds in DMD but fails in GCC. The question is whether it is
something should be changed.
