Description:   Last confirmed: Opened: 2001-08-05 21:06 
Quote from Nathan Sidwell

in main, we copy construct two C objects during the call to Foo.
Foo gets one of these by value, which is dtor'd in Foo. upon return
we dtor the other one. I think this is a problem with the pass-by-value
ABI method. It does look like a bug.
