Correct me if I'm wrong, but I couldn't find anything in the docs that
indicate the following is expected behavior w.r.t. TRAPDEBUG.
Setting TRAPDEBUG seems to make zsh unexpectedly emit SIGEXIT after a
command following a failed && or || conditional expr.
trap "" DEBUG
trap "print exit trap" EXIT
for ((i = 0; i < 2; i++)); do
false && :
echo $?
done
$ zsh ./test.sh
1
exit trap
1
Unsetting debug_before_cmd or having more than one command follow
produces the expected behavior.
Ex:
trap "" DEBUG
trap "print exit trap" EXIT
for ((i = 0; i < 2; i++)); do
false && :
echo $?
:
done
$ zsh ./test.sh
1
1
exit trap
Reproducible since patch 27947.

Hm, it's even weirder than that:
torch% trap "" DEBUG
torch% trap "print exit trap" EXIT
torch% trap
trap -- 'print exit trap' EXIT
trap -- '' DEBUG
torch% false && :
torch% :
exit trap
torch% trap
trap -- '' DEBUG
torch%
Note that the exit trap itself has now disappeared. This happens with
a TRAPEXIT function as well.
