The pass was removed by:
2011-03-23  Richard Guenther  <rguenther@suse.de>

        * Makefile.in (IPA_TYPE_ESCAPE_H): Remove.
        (OBJS-archive): Remove ipa-struct-reorg.o and ipa-type-escape.o.
        (tree-ssa-alias.o): Do not depend on IPA_TYPE_ESCAPE_H.
        (alias.o): Likewise.
        (ipa-type-escape.o): Remove.
        (ipa-struct-reorg.o): Likewise.
        (GTFILES): Remove ipa-struct-reorg.c.
        * alias.c: Do not include ipa-type-escape.h.
        * tree-ssa-alias.c: Likewise.
        * common.opt (fipa-struct-reorg): Preserve for backward compatibility.
        * opts.c (finish_options): Do not reset flag_ipa_struct_reorg.
        * passes.c (init_optimization_passes): Remove ipa-struct-reorg
        and ipa-type-escape passes.
        * tree-pass.h (pass_ipa_type_escape): Remove.
        (pass_ipa_struct_reorg): Likewise.

So closing as won't fix.

Confirmed.
Reduced testcase (crashes with "-O2 -fwhole-program -fipa-struct-reorg"):

=========================================================
template<int> struct A
{
  char c;
  void foo(int);
  void bar(int i) { foo(i+1); }
};

template<int> struct B : virtual A<0> {};

template<int T> inline void baz(B<T>& b, int i)
{
  if (i) b.bar(0);
}

extern template class A<0>;
extern template void baz(B<0>&, int);

int main()
{
  B<0> b;
  baz(b, 0);
  return 0;
}
=========================================================

GCC 4.3.x and 4.4.x segfault, while trunk produced the following ICE:

bug.cc:23:1: internal compiler error: in build_data_structure, at
ipa-struct-reorg.c:3387
Please submit a full bug report, [etc.]

Re-opening as the -fipa-struct-reorg case.
