[PD] comparing symbols in external

[Miller Puckette]

Strange things like this can happen if someone inadvertently writes
a new string into an existing symbol... i.e., never do this:
strcat(sym->s_name, "cat").

MAybe there was already a symbol somewhere else whose name is "cat" and
then you'll have 2 symbols with teh same name but different addresses.
(I've seen people do this, in various ways, before).
