Pl. file bugzilla report (or radar) with a reproducible test case so that we can investigate this linker crash. As you know, one way to control symbol visibility is to use gcc's (inherited by llvm-gcc) visibility support. GCC supports, 1)

Accessing this are direct connections from clients, plus multiple squirrelmail webservers, and pine users, all at the same time with layer4 switch connection load balancing.
