:Any chance you could find out where in zsh's malloc() this is happening?

Possibly something much simpler.

% size zsh
text    data    bss     dec     hex     filename
290784  16384   31524   338692  52b04   zsh

First time through malloc():
 (m = sbrk(4096)) @ mem.c:760  gives   m = 0x53b24

Yay.
