You are sure, you have no mixup with different tcl versions on your system? use always --with-tcl.
The mistake is on your side, we have compiled the whole suite for 64 bit opterons and power5+ (our production environment) an the environment works very stable. if you want that someone helps you with the problem, you have to provide more details about what might be special in your setup.
The troubling question for me is that server seems to have no other issues except "redirect".
Could you suggest any better method to debug this problem?
