Comment (by raimue):

 This must be coming from libc/libSystem and not from bash itself. You
 might be able to use `export OBJC_DISABLE_INITIALIZE_FORK_SAFETY=YES` as a
 workaround (although I am not sure if this actually works when running as
 a login shell in Terminal.app).

 Does this problem also occur when bash is started as login shell with
 `/opt/local/bin/bash -l`? That might make debugging easier as we would be
 able to attach dtruss to see which system calls are responsible for this
 behavior.
