My cursory glance at the FreeBSD implementation of sscanf leads me to believe that it calls strlen just so that it can provide the size for a fake FILE struct that it uses to share an implementation between sscanf and fscanf.

What I don't understand is how the linked commit (https://github.com/libfive/libfive/commit/6c6b4ad91ab1b443969ce8d4300a30e8ecd5d8b2) fixes anything? I see one noticeable change from i=0 to i=1, but otherwise how does that code fix anything?
