[Bug c++/35678] New: partial template specialization ICE in dependent_type_p, at cp/pt.c:15539

[gcc-bugzilla at contacts dot eelis dot net]

Consider:

  template<typename T, T> struct A;
  template<typename> struct B; 
  template<template<typename T, T> class U> struct B<U<char, 'h'> > {};
  B<A<char,'h'> > x;
    // internal compiler error: in dependent_type_p, at cp/pt.c:15539

Comeau 4.3.9 and GCC 4.1.2 accept the code.

------- Comment #2 from sultansharem at gmx dot ch  2008-04-04 22:33 -------
i think i have a fix:

in pt.c
just remove lines 15671-15678 in dependent_type_p. I'm not sure though wether
this breaks something else...
