When returning from a function in an exception handler, the destructor for
objects local to the function is never called.
The attached program returns 0 (as expected) when compiled with:
gcc version 4.4.3 (Debian 4.4.3-3)
The same program returns 1 when compiled with:
gcc version 4.5.0 20100310 (experimental) [trunk revision 157334] (Debian
20100310-1)
