You don't give enough info. I assume you talk about a login into the  
host system and then doing a "jexec X pdksh" to login into a jail. The  
important question here is the how you login into the host system.

So far it is not clear that the bug is within the *ksh. It may be also  
the case that the problem should be fixed somewhere else.
