Core dump bug in ZSH version 3.0.7

[Carl Feynman <carlf@xxxxxxxxxxxx>]

I accidentally pasted a python program into zsh and it crashed it, 
saying "Memory fault (core dumped)".  I cut down the offending python 
code to the following three lines, all of which seem to be required to 
cause the bug:

if (len(sys.argv) > 1) :
mask = (1 << string.atoi(sys.argv[1])) - 1
key = string.atoi(sys.argv[2])

When I put these lines in a file, I can crash zsh by either 'zsh 
bad-file' or, from within zsh, '. bad-file'.  In both cases it prints

command not found: len(sys.argv) [1]
parse error near `)' [2]
Memory fault (core dumped)

This is happening in zsh version 3.0.7.  Uname -a returns
