I am not sure what to do either. Do you think we could have a solution in a reasonable amount of time? I don't want to give up to easily, but it feels like the further we go, the more issue we find (it feels the same way I felt with the objfile search order patch series). We have several options: 1. Ignore the initial regression, and release with it 2. Revert the patch that caused the regression. I can't remember which patch that was, and whether it would "unsolve" an important issue. 3. Ignore the side-effect/regression caused by this fix, and fix it later 4. Delay the release in order to implement setjmp handling. Not being completely up to speed with the issues involved, I am not sure which one would make sense. Delaying the release would have some impact on Maciej's mips work, but is otherwise a real possibility. -- Joel
