Entering a typo such as ${Bazaar.Item[1].Nam} results in a CTD with me, bedugged it and here's what I got:

[MQ2]CCommandHook::Detour(/echo ${Bazaar.Item[1].Nam})
(c50.af50): Access violation - code c0000005 (first chance)
First chance exceptions are reported before any exception handling.
This exception may be expected and handled.

I can't reproduce with any other data types besides Bazaar. One note, Lax said this may be a buffer overflow in mq2bzsrch, thanks.
