Are you saying that you get a segfault when you build with 3.4.3 on RHEL 2.1, but not when you build with 3.4.3 on RHEL 3.0 or RH9? If so, this doesn't sound like the compiler is at fault. A KDE developers' list might be a better place to track this one down, but I don't see any alternative to just debugging the problem. If the blowup is in a place where there appears to be no code, it's probably in a destructor.
