Let's be even clearer: MSVC compiled it, which is also a bug. Seriously, I don't think that either compiler accepted the code in any way as it is, since it just screams incompleteness. Also, notice the smiley on that last paragraph of mine, it wasn't meant too technical.

From: FE on 1 Apr 2010 20:43 sorry . code is: #include <iostream> using namespace std; class null_t { public: template<typename T> operator T*(){return 0;} }NPP; int main(){ if(*NPP)cout<<"*this"<<endl; return 0; } NULL change to NPP; -- [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated.

Perhaps he had NULL instead of NPP? I can see that might cause confusion. IIRC NULL in gcc isn't quite (void *)0; -- [ See http://www.gotw.ca/resources/clcm.htm for info about ] [ comp.lang.c++.moderated. First time posters: Do this! ] |
