These versions have -unique mangled names (they have to, in order for linking to work), but -they have identical source code names, which leads to a great deal of -confusion. Specifically, if you set a breakpoint in a constructor or a -destructor, gdb will put a breakpoint in one of the versions, but your -program may execute the other version.
