Changed alloca -> calloc to fix crash bug.

Browse source 
Also added modestate (will be removed).

btw, something to remember about ALLOCA:
"If the calling function does not contain  any references
to local variables in the stack,  the stack will not be
restored correctly when the function exits,  resulting
in a program crash. "
