Bug #: 11550
Summary: Missing warning for unused variables of a class type
with user declare constructor
Product: clang
Version: unspecified
Platform: PC
OS/Version: Linux
Status: NEW
Severity: enhancement
Priority: P
Component: C++
AssignedTo: [email protected]
ReportedBy: [email protected]
CC: [email protected], [email protected]
Classification: Unclassified
We don't warn about
-------------------
struct S {
S();
};
S foo();
void bar() {
S x = foo();
}
-----------------
gcc 4.6 warns about x being "set but not used", which I don't think is
technically correct, but it is better than nothing.
