Just a random pick from those two possible fixes. It's stored into 'idx'
variable which is int and labs() returns long.  To use labs() the 'idx' would
have to be changed to 'long' or even 'size_t' since it's used only as 'size_t'.

If you think that it would be better to use the labs() and change the 'idx' to
'size_t' I can do that.
