That code is bizarre.
I believe that itoa will explode with any number larger than 9, which is
convenient since I don't think it will ever be called with a number larger
than 9. But that code and everything related to it really needs to be
rethought from scratch.
The first element of the array that's being constructed is a string
representation of the number of items in the array, which is only used as
an argument to atoi in the caller to get the array length. It looks like
someone really wanted a vector, which we now have in libinn. That would
require some fiddling in perm.c, but I think it's probably the clean
