------- Comment #3 from reichelt at gcc dot gnu dot org  2009-11-30 00:37 -------
Reduced testcase (crashes with "-O2" on i686-pc-linux-gnu):

==========================================================================
void foo(const char*);

template<int*> struct A
{
  template<typename T> A(const int&, T);
  int i;
};

template<int* X> template<typename T> A<X>::A(const int& j, T) : i(j)
{
  foo(0);
  foo(0);
  foo(__PRETTY_FUNCTION__);
}

int N;

struct B
{
  B();
  A<&N> a;
};

B::B() : a(N, 0) {}
==========================================================================

The crash only happens on the 4.4 branch.

------- Comment #6 from jakub at gcc dot gnu dot org  2009-12-03 15:59 -------
This happens during mangling something from within the middle-end, and at that
point cfun is a T.0 clone, which has cfun->language = NULL.
Not sure what's the best solution, whether to change current_class_ptr etc.
macros from cfun ? cp_function_chain->* : NULL to (cfun && cp_function_chain) ?
cp_function_chain->* : NULL, allocate a dummy cfun->language somewhere when we
are going to call FE functions that might need it, something else?

gcc44-pr41183.patch

Very ugly hack that fixes this.  Checking for NULL cp_function_chain might be
even uglier though.
