not sure what I'm doing wrong. this external was intended to save a list into memory and then serialize it, but I couldn't get past this hangup.

the lister_listin method crashes PD.

any help, you guys can give me would be great

after poking around I discovered that lister1_listin was receiving something that wasn't argcee for the second argument. after replacing it with a dummy (t_symbol *nada) and shifting argcee and argv right it no longer crashes.
it would be nice if this were documented though
edit: the t_symbol is the selector (set)
