I had tried to compile code like
template<int dim> class cls {
cls<dim-1> c[16];
};
template<> class cls<0> {
};
int main() {
cls<200> c;
return 0;
}
and had error:
g++: Internal error: Segmentation fault (program cc1plus)
Please submit a full bug report.
See <URL:http://gcc.gnu.org/bugs.html> for instructions.
I think, in this case better output maybe something like "no enough memory",
"unable to compile" etc.
