Hi there

(you're Tiago Menezes aren't you?)

you were right about the bug!

the wrong code line is this one

if (d->custom_optind == 1 || d->custom_optind == 0 || !d->initialized) {

which must be changed into

if (d->custom_optind == 0 || !d->initialized) {

I've uploaded this fixed temporary release here

hope to hear from you soon
cheers
