Hi,
now playing with templates I discover new bugs every day,
they become more and more weird from time to time ...
Here is the newest: consider the following program:
/*--------------------------------bug4.C--------------------------------*/
template <int n> class vec {
double x[n];
public:
vec() {
for (int i=0; i<n-1; ++i) x[i]=0;
}
vec(const vec<n>& v) {
for (int i=0; i<n; ++i) x[i]=v(i);
}
vec(const vec<n-1>& v, const double& y) {
for (int i=0; i<n-1; ++i) x[i]=v(i);
x[n-1]=y;
}
inline double operator()(const int i) const {
return x[i];
}
};
template <int n> vec<n>& operator,(const vec<n-1>& v, const double& y) {
return *(new vec<n>(v, y));
}
int main() {
vec<4> v;
vec<5> w;
w=(v,3.);
}
/*--------------------------------bug4.C--------------------------------*/
The compiler accepts the code, but the assembler refuses to work.
I got the following error message from the (ix86-)assembler:
In case anyone else is in danger of getting over-eager, I'm about to
go to work on this problem. We don't mangle things correctly, and
that's why we get these assembler messages. I should have a patch
reasonably soon (by sometime next week at the latest).
