[Bug c++/32251] New: [4.1/4.2/4.3 regression] ICE on delete operator with ellipsis

[reichelt at gcc dot gnu dot org]

The following code snippet triggers a segfault since GCC 3.4.0:

=======================================
struct A
{
  A();
  void operator delete(void*,...);
};

void foo()
{
  new A;
}
=======================================

bug.cc: In function 'void foo()':
bug.cc:9: internal compiler error: Segmentation fault
Please submit a full bug report, [etc.]

Before we got an error message:
bug.cc: In function `void foo()':
bug.cc:9: error: no suitable `operator delete' for `A'

I'm not quite sure, but I think the code is valid after all.
