BUG: permanent allocation in mathevall

["Bart Schaefer" <schaefer@xxxxxxxxxxxxxxxxxxxxxxx>]

I'm getting the "BUG: permanent allocation in mathevall" message every time
my TRAPALRM function fires.

TRAPALRM () {
        TMOUT=60 
        title
}

It's happening below getiparam("TMOUT"):

#0  mathevall (s=0x819cea0 "6", prek=17, ep=0xbffff0b8)
    at ../../zsh-3.1.6/Src/math.c:852
#1  0x8075097 in matheval (s=0x819cea0 "6") at ../../zsh-3.1.6/Src/math.c:913
#2  0x80750ef in mathevali (s=0x819cea0 "6") at ../../zsh-3.1.6/Src/math.c:924
#3  0x807a710 in getintvalue (v=0x80f6340) at ../../zsh-3.1.6/Src/params.c:1368
#4  0x807b2c5 in getiparam (s=0x80cee62 "")
    at ../../zsh-3.1.6/Src/params.c:1603
#5  0x80875f5 in handler (sig=14) at ../../zsh-3.1.6/Src/signals.c:526
#6  <signal handler called>
#7  0x4009c6f4 in __read ()
#8  0x80a6607 in getkeybuf (w=0)
    at ../../../zsh-3.1.6/Src/Zle/zle_keymap.c:1191

Unfortunately, I'm not sure what to do about it.  I believe signal handlers
deliberately avoid using the heap because of issues about when it should be
popped, but I don't recall for certain.
