[analyzer] pr32088: Don't destroy the temporary if its initializer causes return.
In the following code involving GNU statement-expression extension:
struct S {
~S();
};
void foo() {
const S &x = ({ return; S(); });
}
function 'foo()' returns before reference x is initialized. We shouldn't call
the destructor for the temporary object lifetime-extended by 'x' in this case,
because the object never gets constructed in the first place.
The real problem is probably in the CFG somewhere, so this is a quick-and-dirty
hotfix rather than the perfect solution.
A patch by Artem Dergachev!
