My apologies for the disruption; if you sent anything and it bounced
(or didn't come back), you'll have to resend it (this includes address
changes).
The spam (and the aftermath) have been purged from the archives. I've
taken this opportunity to put the latest versions on the ftp site,
ftp.sys.utoronto.ca. I've also rolled over the archives as well (into a
somewhat misnamed 'rc-list.1994.gz' file); in the future, I'll try to do
this yearly.

A while back Byron asked if I had the patch handy for a bug in the
reader that someone noticed. Sorry for the delay, here's the diff.
This diff also works around a bug in ObjectCenter's understanding of
declarations. I know of a few other bugs, in the print library, but I
think they are benign. [The fixes for those are reflected in the
version of the print code that I sent to comp.sources.unix a while
back, if anyone wants to integrate them. (Yeah, I ought to do it.)]

When I first read this, I was a little surprised to see that such a bug
existed in so reliable a piece of code as rc. So surprised that I tried
it and couldn't reproduce the problem. I was in the middle of replying
when I saw that my reply was going to 9fans and not the rc list.
Kudos to Byron for building a more robust clone than the original.

Subject: Need help with rc on Linux
Hello rc users,
I'm having a strange rc problem which I believe is related to my
"port" of rc to Linux. Briefly, I have a 486 box running Linux 1.1.54
with the rc-1.5betadev-1 distribution of rc. I compiled rc using the
notes from Jeremy Fitzhardinge from the rc mail archives. I think I
did get a few compiler warnings, but my rc has always seemed stable
except for this.
The problem is in an rc shell script for a simple WWW chat system. It
is executed from NCSA httpd 1.3. Any time I do something along the
lines of "a=`{some_command}" the script freezes. It works fine from
the command line, and in a shell script executed from the command
line. If I pipe some_command to a temp file, then say "a=`{cat
temp}", this often works (but sometimes still freezes).
I'm assuming the problem is in my port to Linux since I've used rc on
my Sun4 at work for two years with no problems whatsoever, and the
same shell script works fine under httpd on the Sun. When compiling
for Linux I admit
Any information about this problem would be greatly appreciated. In
particular if you have a solid Linux version of rc, or diffs for one,
or you've done any WWW stuff using rc and Linux, I'd love to hear from
you.
Thanks in advance folks.
Gary

Subject: rc-1.4 leaks under NetBSD 1.0 on SPARCStation 2
Date: Thu, 4 May 1995 09:31:17 -0400
Sender: smd@chops.icp.net
Message-Id: <95May4.093127-0400_edt.20652+4@chops.icp.net>
Well, I've tried beating it up all over the place,
and am about to see if it might be a complier problem
(NetBSD 1.0 uses gcc version 2.4.5).
Has anyone else used rc on such a setup, and
have you noticed this memory leak also?
It gets quite serious; I only discovered it one day
after rc had eaten up about 40Mbytes of memory... :(
This is obviously operating-system dependent, as the same
rc-1.4 source tree works just fine under StunOS on the same box.
Any help *enormously* appreciated!
Sean.

The online version will still be available via ftp at:
