It is almost fixed on tree-ssa branch, the only thing left is to make sure that the variables get 
spilled into the stack.

The problem is that GCC likes to commit stuff to the stack too early, this will be fixed for the tree-
ssa but right now it is not fixed.

Here is valid (correctly initializing "a") code which shows the problem on the tree-ssa and on the 
mainline:
struct A {
  char const* src;
  char* dest;
  void copy() { *++dest = *++src; }
};

void g1(A *b) {
  A a = *b;
  for(int i = 0; i < 10; ++i)
    a.copy();
}

void g2(A* b) {
  A a = *b;
  for(int i = 0; i < 10; ++i)
    *++a.dest = *++a.src;
}

Suspending based on this is fixed on the tree-ssa.
