Yea, since the soname was the same, I was under the impression that mixing would be fine, and I never ran into a problem. Now that I have unmasked it and more people are testing, I see that people are actually running into issues. So, my mistake. Sorry. If you are doing any upgrade of GCC that is something like 3.3->3.4, or 3.4->4.1, recompiling everything is probably a good first step to ensuring your system will be sane. We try to cut down on work that people will have to do and see if mixed installs will work, but in this case, I was wrong that you would be able to do that. > >If these are the type of problems we're going to see with 4.1.1, I > >would have to vote that it stay masked. > > Yep. I've yet to see cause for saying this. Moving to a completely new version of gcc, as in 3.x -> 4.x, is a huge move. I think the small amount of problems that we are seeing now is great, and if you are using ~arch, you should expect little bumps in the road. We can only do so much testing in p.mask, and all of the people using it there were telling me that it was working fine for them. > > "Testing" isn't even the word > >for this so far.

Just following the GCC Upgrading Guide [1], and you should be fine. There will always be a few people that run into problems, and there isn't much we can do about that. If you think you found a real bug, please report it, or we can't ever fix it.
