Hello, I was just wondering around code and following code resulted in ICE (MinGW 3.4.2). I don't think that this is some kind of terrible bug as the code is obviously wrong (or isn't it?). Maybe you'll want to know about it, at least the compiler want me to report bug :) Maybe someone already reported it ...unfortunately have no time to browse buglists... :(
The error message is: g++.exe -c main.cpp -o main.o -I"C:/Code/Dev-Cpp/include" -I"C:/Code/Dev-Cpp/include/c++/3.4.2" -I"C:/Code/Dev-Cpp/include/c++/3.4.2/backward" -I"C:/Code/Dev-Cpp/include/c++/3.4.2/mingw32" -I"C:/Code/Dev-Cpp/lib/gcc/mingw32/3.4.2/include" -save-temps -Wall main.cpp: In member function `virtual const int iii::get_callback() const': main.cpp:13: internal compiler error: in lookup_member, at cp/search.c:1288 Please submit a full bug report, with preprocessed source if appropriate. See <URL:http://www.mingw.org/bugs.shtml> for instructions.make.exe: *** [main.o] Error 1 Yes I know it says to contact MinGW but I think the ICEs are better to submit to GCC directly, aren't they? The codes are: --- main.cpp --- #include <stdlib.h> #include <stdio.h> #include "cProperty.tcc" class iii : public property<int> { public: iii() { }; iii(int i) : property<int>(i) { }; protected: const int get_callback() const { printf("my getcb\n"); return this->property<int>; // this causes the ICE }; }; int main(int argc, char *argv[]) { iii *i = new iii; printf("::: %d\n", (int)*i ); *i = 1; printf("::: %d\n", (int)*i ); delete i; system("PAUSE"); return 0; }; --- EOF --- --- cProperty.tcc --- #ifndef CPROPERTY_HPP #define CPROPERTY_HPP template <typename T> class property { private: T _p; protected: virtual const T get_callback() const { printf("getcb\n"); return _p; }; virtual const T set_callback(const T& p) const { printf("setcb\n"); return p; }; public: property() { }; property(const T &p) { this->_p = set_callback(p); }; virtual ~property() { }; virtual operator T() const { return get_callback(); }; virtual const T& operator=(const T &p) { return this->_p = set_callback (p); }; }; #endif --- EOF --- Well, there is a lot of code that could be stripped but I hope you can browse through it.
