As demonstrated by this PR and Richard's | problems with POOMA, tweaking the GC is simply like opening a can of worms and | we have neither the time nor the resources to deal with that on the 3.3 branch. I appreciate all your hard works and time on this issue. I queue your proposed patch for 3.3.5. It won't make it into 3.3.4, unfortunately. The alpha-dec problem will the last one to be solved for 3.3.4. Richard's problem with POOMA is a _long_ standaing problem starting with 3.3.0. It is not triggered by a recent patch. It just happens that many bugs are intertweaned. I really want to help solve this problem, but I don't think we should revert Dave's or Zdenek's patch. I want to help all interested parties to get forward. -- Gaby -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14671
