>Description:
The dtor of an auto variable outside a try loop is not called when an
uncaught exception inside the try loop unwinds.
>How-To-Repeat:
This simple test code can reproduce the problem.
The output should be:
A()
~A()
Got long 0
Instead the output is
A()
Got long 0
------
#include <iostream.h>
class A {
public:
A() {
cerr << "A()" << endl;
}
~A() {
cerr << "~A()" << endl;
}
};
void f() {
A a;
try {
throw long(0);
}
catch(int&) {
cerr << "Got int exception" << endl;
}
}
int
main(int,char**) {
try {
f();
}
catch(long& v) {
cerr << "Got long " << v << endl;
}
return 0;
}
