Bug Description
Typing a '#' character at the start of the line at the interactive prompt, followed by any other character (except if it is deleted by using backspace, Ctrl-U, etc.) causes ksh to immediately segfault and coredump. If you use Ctrl-V to input a control character literal, it doesn't crash on Ctrl-V, but the next character. Core dump is attached.
Ubuntu 12.04.1, ksh 93u-1.
