the issue was that 'int_a' label was assigned to trees with different
meanings. One, was a tree that has the int value immediately
available and the other---contains the other 'int_a' tree.
The fix was to remove this double 'int_a' tree. This way, we can
handle all 'int_a' trees as if they have the value immediately.
The rest of the changes is removing stray, extra whitespaces
