 Here's a reduced testcase:
 
 ----------------------------snip here-------------------------------
 void* operator new(unsigned int, void*) throw();
 void operator delete (void*, void*) throw();
 
 struct A { A(); };
 
 struct B
 {
    struct X
    {
       ~X();
       operator void* () const;
    };
 
    X bar();
 };
 
 struct C
 {
    B b;
 
    C(A&) { new(b.bar()) A; }
 };
 
 void foo()
 {
    A a;
    C c(a);
 }
 ----------------------------snip here-------------------------------
 
 This one crashes gcc 3.0.x, gcc 3.1 - gcc 3.2.1:
 
 bug.cc: In constructor `C::C(A&)':
 bug.cc:21: Internal compiler error in convert_from_eh_region_ranges_1, at
    except.c:1404
 Please submit a full bug report, [etc.]
 
 However, it does not crash gcc 2.95.3 (regression!) and mainline.
