I cannot speak to the problem at hand, and have not looked at the zsh
code in question, but ceteris paribus, this line of reasoning is faulty.

When a "problem disappears", that does not mean that another one,
elsewhere, doesn't move to take it's place. Example: heap corruption due
to bad pointer management with optimization on, but valid memory getting
trashed with optimization off/debugging on.
