Next step is to see if that code chunk on its own is responsible,

 typeset MANPATH
 manpath=(/ /)
 typeset -UT MANPATH manpath
 print $manpath

--- that's going to need to be within a function to have the right
effect, so

() {
  typeset MANPATH
  manpath=(/ /)
  typeset -UT MANPATH manpath
  print $manpath
}

--- or if there's some precursor, and if the latter whether $manpath is
accessible without a crash at the end of the previous test.  If yes to
both it's going to be interesting, but that seems unlikely.  If there's
a precursor hopefully it's some previous assignment to manpath or
MANPATH that can be tracked down and added to the above by hand.
Printing out "$manpath $MANPATH ${(t)manpath} ${(t)MANPATH}" at the top
of the test (before it starts crashing) might or might not help.

Presumably, then, the bin_typeset call is leaving manpath in a bad
state.  This is certainly a somewhat hybrid case as manpath is a special
while -T is for user tying --- so this could be down to consistently
making sure the specialness stays.  It's not clear from what I've seen
so far if the valgrind error is actually within the above code.
