The problem with the storing on the stack is still fixed but there is a different issue which 
the tree-ssa should have fixed:
<L24>:;
  <D1819>_176 = 0;
  goto <bb 9> (<L26>);

  if (T.4_164 > T.6_165) goto <L24>; else goto <L25>;
<L25>:;
  <D1819>_175 = 1;

  # <D1819>_2 = PHI <1(8), 0(7)>;
<L26>:;
  T.31_166 = (bool)<D1819>_2;
  T.31_167 = T.31_166;
  if (T.31_166) goto <L15>; else goto <L27>;

Looks like the jump thread for some reason is not doing its job here.
