First, please post the output of `uname -a`. It'd be useful to know when you
grabbed sources last, if you've built your own world at all, as well. This
information is necessary before we continue. Also please post the output from
the commands `ls -l /bin/csh` and `md5 /bin/csh`.
While in sh, if you type /bin/csh to run csh, does it crash, or does it seem
proper? If it seems proper, try and few commands and see if it still does.
If it crashes, let's try some debugging. You should have a csh.core file,
probably in /root. Run the command `gdb /bin/csh /root/csh.core` (replacing
/root/csh.core to whatever path csh.core is in, if it's not in /root), and post
the output to this list along with everything else I've asked for.
Do that now. If that still doesn't work, I'm going to tell you to...
Build it for debugging. cd to the directory /usr/src/bin/csh, and run the
following commands: `CFLAGS='-ggdb' make`, then run `make install`. Once
that's done, try /bin/csh again and if it crashes again, run `gdb /bin/csh` -
when it crashes this time
If you do not have a directory called /usr/src/bin/csh, you'll need to cvsup
your src. Check through /usr/share/examples/cvsup/stable-supfile and the
handbook section on updating sources via cvsup. Once that's done, go back and
run the commands in the following paragraph.
Clearly, something is very wrong here.
Note to others:
-rw-r--r-- 1 root wheel 4895 Mar 19 2006 /usr/src/bin/csh/Makefile
-rw-r--r-- 1 root wheel 6882 May 16 2007 /usr/src/bin/csh/config.h
-rw-r--r-- 1 root wheel 2964 May 16 2007 /usr/src/bin/csh/config_p.h
-rw-r--r-- 1 root wheel 28287 Apr 6 2004 /usr/src/bin/csh/host.defs
-rw-r--r-- 1 root wheel 1873 Feb 19 2006 /usr/src/bin/csh/iconv.h
-rw-r--r-- 1 root wheel 2391 Feb 19 2006 /usr/src/bin/csh/iconv_stub.c
Those are the file modification times for the csh sources, so even if he's
running an older -RELEASE there shouldn't be any incompatibility issues with
the latest source tree.
