[Bug tree-optimization/40642] New: [4.5 regression] ICE with -fprofile-generate

[bangerth at gmail dot com]

This is a regression in at least current mainline over 4.2. I can't check
4.3 and 4.4 for the moment. I found this working on a successor to the
447.dealII benchmark to be included in the next SPEC testsuite. It triggers
about half a dozen times on that code base.

Either way, here it is:
---------------------------
#include <vector>                                                               

void foo ()                                                                     
{                                                                               
  std::vector<std::vector<std::vector<int> > > v(3);                            
  for (unsigned int d=0; d<3; ++d)                                              
    v[d].resize (13);                                                           
}
---------------------------

------- Comment #1 from reichelt at gcc dot gnu dot org  2009-07-05 23:59 -------
Confirmed. Reduced testcase (crashes with "-O2 -fprofile-generate"):

========================================================================
inline void* operator new(__SIZE_TYPE__, void* p) throw() { return p; }
inline void operator delete (void*, void*) throw() { }

template<typename T> void foo(void* p, T t)
{
  new(p) T(t);
}

void bar();

template<typename T> struct A
{
  T* p;

  A() { try { foo(p, T()); } catch(...) {} }

  A(const A&) { try { bar(); } catch(...) { throw; } }
};

A<A<int> > a;
========================================================================

The bug appeared between 2009-04-24 and 2009-05-09.

Can you try this again?  I think this has been fixed already as these testcase
works for me.
