The following invalid code snippet triggers an ICE since GCC 4.4.0:
======================================
template<int> struct A
{
int i;
friend void foo() { int x[i]; }
};
struct B
{
int j;
friend int bar() { return j; }
};
======================================
bug.cc: In function 'void foo()':
bug.cc:3:7: error: invalid use of non-static data member 'A<<anonymous> >::i'
bug.cc:4:29: error: from this location
bug.cc: In function 'int bar()':
bug.cc:9:7: error: invalid use of non-static data member 'B::j'
bug.cc:10:29: error: from this location
bug.cc:10:29: internal compiler error: tree check: expected class 'expression',
have 'exceptional' (error_mark) in fold_build_cleanup_point_expr, at
