This is required by the C++ ABI. It is, in my opinion, a real bug that gcc does not simply merge identical constructors. There are ABI issues with changing, in that it can change the behaviour of existing code in some very subtle ways that will probably not break any actual existing code. We should at the very least offer this as an ABI_-breaking option for people using embedded systems or other cases where code size matters. There is a bug report at http://gcc.gnu.org/PR3187 . The last patch I know of related to this was http://gcc.gnu.org/ml/gcc-patches/2007-11/msg01147.html . > 00000000 <_ZN1TC2ERKSs>: > 0000000c <_ZN1TC1ERKSs>: Note that although the demangler demangles them to the same string, the two functions have different names.
