            Bug ID: 58859
           Summary: throwing exceptions in destructors causes
                    std::terminate called too early.
           Product: gcc
           Version: 4.8.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: c++
          Assignee: unassigned at gcc dot gnu.org
          Reporter: meng at g dot clemson.edu

the following program does not execute (2) for g++-4.8.[01] -std=c++11 and I
think this is a bug. I tested the program on g++-4.[67].[01] with or without
c++11 enabled, and g++-4.8.0 with c++11 flag, and in VS 2010, in all these
cases, (2) was executed and the program finished without a call to
std::terminate. My understanding is that the throw expression happens before
stack unwinding and that there is a matching handler, therefore, std::terminate
should not be called.

----------------------- BEGIN -----------------------
#include <iostream>

struct test_t
{
 test_t () { std::cout << " test_t @ " << this << std::endl; }
~test_t () { std::cout << "~test_t @ " << this << std::endl; throw 0; }
};

int main ()
{
 try
 {
  test_t const t; // (1)
 }
 catch (...)
 {
  std::cout << __LINE__ << std::endl; // (2)
 }
}
-----------------------  END  -----------------------
