Pardon me for asking when I haven't had a chance to try it yet, but does
this work right if redirection of the same FD appears both at the time of
def'n and at the time of call?

E.g. in bash:

foo() { echo foo; } >&3
foo 3>&2

first dups 3 from 2 and then dups 1 from 3, so "foo" is echo'd to stderr.

By dump files do you mean zcompile?
I fear I'm not of much help there.

I wouldn't expect any that would fool valgrind on a few simple examples.
