Problems with zsh 3.1.9 and cygwin

[Mike Boilen <mboilen@xxxxxxxxxxxxx>]

I am using windows 2000 server with cygwin 1.1.2 (or whatever the newest
release is; I downloaded it yesterday).  The code for zsh 3.1.9 builds fine
without modification.  However, when I run it, I get the error:

      0 [main] zsh 18877 handle_exceptions: Exception:
STATUS_ACCESS_VIOLATION
    913 [main] zsh 18877 stackdump: Dumping stack trace to zsh.exe.stackdump

and the following stackdump:

I also poked around the code a bit.  It appears to crash in params.c at line
508 (using gdb to discover this)
    for (envp = new_environ, envp2 = environ; *envp2; envp2++) {

It parses several environment variables correctly, and then crashes.  All
the memory addresses look fine (i.e. none are null).  However, I'm a unix
programmer, not a windows programmer, so I don't have a good sense of what
"valid" really looks like.

Any ideas what could be causing this?

Thank you very much for your help.
