[Bug c++/21025] New: ICE on template

[algrant at acm dot org]

3.4.3 seg faults on this:

  template<int N> struct X { char x[N]; };
  template<typename T> X<1 + sizeof(T) - sizeof(T)> F(T const &);
  template<int N> struct S { int d() { F(1); } };

Appears to be quite dependent on the fact that the template argument
involves "sizeof(T) - sizeof(T)" - if the - is changed to a +, it works.
Ok in 3.3.2, and ok if S is not a template.

------- Additional Comments From pinskia at gcc dot gnu dot org  2005-04-14 16:52 -------
Confirmed.

It also worked with "3.4.0 20040116" which means it was broken after the branch of 3.4.0.
