The following code caused g++ syntax error. All strings in the 'main' are
functionally the same. The second one differs from the first only by parens
added around the rh expression. The last one differs in the way a casting
operator is expressed. 1 and 3 lines are OK. The second gives the following:
>> gcc/3.3.2/bin/g++ -c -I$sclasssrc -I$common/include e.cxx
e.cxx: In function `int main()':
e.cxx:16: error: parse error before `<<' token
Here is the code:
template <int MSB, int LSB>
struct Data {
Data();
operator unsigned ();
};
template<int EXTMSB, int EXTLSB>
struct Funct : public Data<EXTMSB - EXTLSB, 0> {
template<int MSB, int LSB>
Funct(const Data<MSB,LSB> &src);
};
Data<88,0> abc;
int main() {
unsigned x;
//x = unsigned(Funct<20,20>(abc)) << 1; // works
x = (unsigned(Funct<20,20>(abc)) << 1); // does not work
// x = ((unsigned)Funct<20,20>(abc) << 1) ; // works
return 0;
}
It produces the same error in 3.2.2
