Subject:	Seqfault doing kill -l
Mime-Version:	1.0

Hi,

Couldn't find a mention of this in the Cygwin mailing list archives and
thought I'd ask about it. 

I was trying to get the list of siginals that cygwins kill (/bin/kill)
takes using the kill -l command (and --list). Unfortuantly it causes it
to segfault as you can see from the following output, thought the other
kill in /usr/bin/kill works okay. Is this a known issue?

robertm AT al ~
$ /bin/kill --list
Segmentation fault (core dumped)

robertm AT al ~
$ /bin/kill --version
kill (cygwin) 1.14
