3.0.8 math bug?

[Dan Nelson <dnelson@xxxxxxxxxxxx>]

Why does evaluating a non-numeric variable cause 3.0.8 to consume all
available RAM and then exit to the parent shell?  At least 3.1.9
doesn't completely exit, but I would expect invalid variables to
evaluate to 0 just like unset variables do.

(dan@dan)/tmp> zsh -f
dan% echo $ZSH_VERSION
3.0.8
dan% a=a
dan% (( a ))
zsh: fatal error: out of memory
(dan@dan)/tmp>

(dan@dan)/tmp> zsh31 -f
dan% echo $ZSH_VERSION
3.1.9
dan% a=a
dan% (( a ))
zsh: math recursion limit exceeded
dan%
