Took a quick look at that -- the stack traces aren't very useful
because zsh was not compiled with debugging symbols, so no line
numbers or source file names.  However, there have been literally no
changes to the code where you're encountering the error (zrefresh et
al) since 5.4.1, so there must be a bad allocation somewhere else that
is only manifesting when you reach that point.

In fact it's pretty likely to be some kind of signal-management thing
causing malloc re-entrance.
