But the most probably culprits are either j or lambda[j-1]
or whatever the INDEX_OF macro(is it a macro?) is doing behind 
what is visible.
There is no (direct) use of the function args on line 118.
Of course, it might be that e.g. an uninitialised arg (e.g. no_eras
might be unitialised and get a random value 22) might result later in j
or whatever being initialised.
