The following snippet makes GCC 4.3.2 (and SVN versions as of 09/2008 still)
cause an ICE:
template <typename T, T N> void f(T(&)[N]);
int main() {
int x[2];
unsigned int y[2];
f(x); // works
f(y); // ICE
}
Getting this output:
test.cpp: In function 'int main()':
test.cpp:7: internal compiler error: in dependent_type_p, at cp/pt.c:15585
