Bug ID: 57930
Summary: missing destructor call after thrown exception in
C++11 list initialization
Product: gcc
Version: 4.9.0
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: mmehlich at semanticdesigns dot com
In the example below, a subobject of type B is constructed but not destructed
when an exception is thrown during construction of the enclosing object of
type A after subobject of type B has been constructed.
extern "C" int printf(const char *,...);
struct B {
B(int,int) { printf("CB %p\n",this); }
B(const B&) { printf("const CB %pn\n",this); }
B(B&&) { printf("const CB %pn\n",this); }
~B() { printf("B %p\n",this); }
};
struct C {
int c;
int c2;
};
struct A {
struct B b;
struct C c;
};
A test() {
//const A a1 = { { 1, 2 }, { 3, (throw 9, 4) } } ; // destructor for B
called
//const A &a2 = { { 1, 2 }, { 3, (throw 9, 4) } } ; // destructor for B not
called
return { { 1, 2 }, { 3, (throw 9, 4) } } ; // destructor for B not called
};
int main() {
try {
test();
} catch (...) {
}
}

I'm pretty sure there's an existing bug report about this, opened by Jason.

Maybe we have another one too, but isn't this PR57510?

Yes, that's probably the one I'm thinking of.
