Bug ID: 82900
Summary: Warn on initialization with self
Product: gcc
Version: 8.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: antoshkka at gmail dot com
Target Milestone: ---
Following code
struct Y { Y(Y&){} };
int main() {
Y y(y);
}
Produces a useful warning on clang:
warning: variable 'y' is uninitialized when used within its own initialization
[-Wuninitialized]
Y y(y);
~ ^
It would be nice to have this warning in GCC, especially because this case may
produce unexpected results after implementing Bug 82899
