The fre2 dump looks much nicer (the .optimized dump is a bit surprising, I
would need more time to look at it). It is not sufficient, but it clearly
helps.

In the fre2 dump, I still see (skipping many lines, I may have skipped some
essential ones):

  D.2325.o = _4;
  D.2325.o = _101;
  _105 = _4;
  __builtin_free (_105);
  _96 = D.2325.o;

(instead of _96 = _101)
