It does in the AIX 7 version that I built, yes.

It's linker magic.  Both the system malloc and the ralloc.c-supplied 
malloc are available, and both are used: Emacs uses the ralloc version 
and library functions like XFreeFontNames use the system malloc.

This mixture of system and ralloc-supplied malloc might be causing 
Gilles's problem, which is partly why I suggested that he build with the 
system malloc only.
