[Bug c++/34158] Template delete doesn't call if exception thrown in constructor

["steve_cheng at scotiacapital dot com" <gcc-bugzilla@gcc.gnu.org>]

------- Comment #3 from steve_cheng at scotiacapital dot com  2008-05-23 13:41 -------
I have hit the same bug as the original reporter.  
Attached is a simplified test case.  Run with:

$ g++ -v -save-temps -o testPlacementDelete testPlacementDelete.C 
$ ./testPlacementDelete
placement new called
exception caught

Expected output should be instead:
placement new called
placement delete called
exception caught

Note that the placement delete is called if the extra argument to placement new
and delete is a non-templated type.  It fails when the extra argument is a
templated type.

I am running on:
