Hi. I'm seeing some "weird" stuff with my 4.0-STABLE box. The
symptom is:
tim:/tmp$ gdb /bin/pwd
GNU gdb 4.18
[License]
This GDB was configured as "i386-unknown-freebsd"...
(no debugging symbols found)...
(gdb) run
Starting program: /bin/pwd
warning: shared library handler failed to enable breakpoint
/usr/home/tim
Program exited normally.
(gdb)
It prints "/usr/home/tim", even though I was in "/tmp" when I ran
it.
It's not gdb, I'm quite sure. A 3.4-STABLE box doesn't do this. I
started trying to figure this out because I was trying to use cook
(/usr/ports/devel/cook), and any recipe that redirected output to
a file would put that file in my home directory, no matter where I
ran cook from.
For example, when I run the following script I get:
tim:/usr/tmp/junk$ sh thetest.sh
/* Howto.list, /tmp/cook-test, Mon Apr 10 02:03 2000 */
cook: pwd > junk
cook: ln -s /tmp/cook-test not-junk
1c1
< total 8
---
> total 9
6a7
> -rw-r--r-- 1 tim tim 10 Apr 10 02:03 junk
/home/tim
lrwxr-xr-x 1 tim wheel 14 Apr 10 02:03 /tmp/cook-test/not-junk -> /tmp/cook-test
Here's the script:
#! /bin/sh
test -e /tmp/cook-test && rm -rf /tmp/cook-test
mkdir /tmp/cook-test || exit 2
cd /tmp/cook-test || exit 2
cat <<EOF > Howto.cook
all: junk not-junk ;
/* this will create a file in my home directory! */
junk:
{
pwd > junk;
}
/* this does what I want it to - put a symlink in the current dir */
not-junk:
{
ln -s `pwd` not-junk;
}
EOF
/bin/ls -l $HOME > before
cook
/bin/ls -l $HOME > after
diff before after
cat $HOME/junk
ls -l /tmp/cook-test/not-junk
exit 0
I don't know what these two things have in common. Make can redirect
output just fine. The shell does just fine, too. I'm trying to run
through the source code for cook to see exactly what it does, but I
haven't traced the problem yet. I don't even know where to start with
looking at gdb's code.
tim:/home/tim$ uname -a
FreeBSD threads.polyesthetic.msg 4.0-STABLE FreeBSD 4.0-STABLE #3: Tue Mar 21 02:31:14 EST 2000 root@threads.polyesthetic.msg:/usr/src/sys/compile/THREADS i386
I'm wondering, is anyone else seeing this? Can anyone give me a hint
about where I should be looking to track this down? I haven't seen
any mention of it in -stable, -current or -bugs.
If you're not seeing this, I'd appreciate your letting me know that,
too, so I can narrow down the number of things I have to look at.
Thanks a lot,
Tim
