According to hdrs/filter.h the filter program is limited to a maximum of
"only" 25 rules.  I suspect you overran an array but still within the
program's data area.   Around rule 29 or 30 you were actually getting
your sadistically data overwritten by the legitimate owners/variables of
that memory space.
