if it's any help, note that adding -static-libstdc++ to the compile 
flags changes the output.

without -static-libstdc++:
void* operator new(size_t) 18

with -static-libstdc++:
void* operator new(size_t) 18
void* operator new(size_t) 18
void operator delete(void*) 23
void operator delete(void*) 23
