[mapserver-dev] Checks in msFreeCharArray

[martin.kofahl at gmail.com]

Hello,
I tamper with some cases, where ‎msFreeCharArray is called, but the array was already freed, although num_items is still >0. (The join code.) I would prefer msFreeCharArray checks if array still exisist and sets it to null instead of doing this in the caller functions.

Would this be ok?
