Problem with CCTextFieldTTF

If I input too many characters(about 30 characters) the program seems run into a endless loop. Is it a Bug?

The Test: TextInputTest also has the Problem with more characters, about 50

the app crashes when you input over 90 characters!

Cocos2d: cocos2d: WARNING: Image (8192 x 128) is bigger than the supported 4096 x 4096

Because labels are drawed into a texture, and OpenGL has limitation of texture size.

A max value setter of input characters would be a nice feature!
