[Bug c++/22293] New: [4.0/4.1 regression] ICE declaring destructor as friend

[reichelt at gcc dot gnu dot org]

Since gcc 4.0.0 the following code snippet causes a segfault:

\x13================================
struct A
{
    friend ~A();
};
=================================

  bug.cc:3: internal compiler error: Segmentation fault
  Please submit a full bug report, [etc.]

The compiler used to give a warning before:

  bug.cc:3: warning: member functions are implicitly friends of their class

Confirmed.  This was introduced after "20041124" but before "20050225".

This is invalid code.
The following is still invalid code (but closer to legal code):
struct B
{
  ~B();
};
struct A
{
    friend ~B();
};

Add B:: infront of the destructor fixes both the ICE and validness of the testcase.
