It might be instructive to know the value of j at that point.

Just some thoughts...
I would think you should create the arrays before you start the
thread.

And I would change this

>  for (int j=0; j < mLength ; j++){
>    array = thearray[j];
>    delete[] array;
>  }
to this
	while(  mLength-- ) //mLength no longer needed
		delete[] theArray[ mLength ]; // reverse order of new

I would also make "array" a local variable instead of an object
member.  At least, the code you gave doesn't require a member named
"array".

Don't know if any of that will fix your problem, but I'd start there.
