Hi,
I upgraded to cygwin1.dll snapshot version 20040218 and 2004020 (due to
problems with zsh and cygwin-1.5.7.1):

CYGWIN_NT-5.1 SINDBAD 1.5.8s(0.110/4/2) 20040218 17:35:06 i686 unknown unknown Cygwin

Now I find that I can suspend a process running vim only once by Ctrl-Z
- after restarting the process, hitting Ctrl-Z any more won't work.
The terminal window flickers for a moment, but the editor is not
suspended.
Suspending a lynx process more than once works fine, while suspending
mutt results in a crash:

4 [sig] mutt 1152 handle_threadlist_exception: handle_threadlist_exception
called with threadlist_ix -1
Segmentation fault (core dumped)

with stackdump:

End of stack trace

This is with an empty home directory, i.e. only the standard shell and
terminal settings from Cygwin, and it happens with bash, pdksh and zsh
(where the latter crashes also with the same error message when
suspending vim if the editor is called from within a shell function,
please see my other posting).
