bad awk output on vkernel
Hello.
Am I only one, or is anyone else seeing this problem too?
I don't remember when, but running `make buildworld' in vkernel stopped
working a few months ago. It always fails while it's building gcc4.4
in _gcc44_tools. I managed to narrow down to an awk script in gcc producing
inconsistent output, here's the script which can reproduce the behavior:
#!/bin/sh
prefix=/usr/src/gnu/usr.bin/cc41/cc_prep
cc41contrib=$prefix/../../../../contrib/gcc-4.1
list=`seq 0 20`
first=
while :; do
last=$(env - PATH=$PATH \
/usr/bin/awk -f $cc41contrib/gcc/opt-gather.awk \
$cc41contrib/gcc/c.opt \
$cc41contrib/gcc/common.opt \
$cc41contrib/gcc/config/i386/i386.opt)
md5=$(echo "$last" | /sbin/md5)
echo $md5
if [ -z "$first" ]; then
first="$last"
first_md5=$md5
elif [ "$md5" != "$first_md5" ]; then
echo "$first" > first
echo "$last" > last
break
fi
done
Things I've already tried include:
- running the same script on native DragonFly box (always constistent md5)
- running on an SMP and non-SMP VKERNEL (both reproduced the problem)
- md5 on the source tree is always consistent
- running this script for source tree in the local filesystem on vkernel,
and on an NFS-exported on from vkernel host (both reproduced the problem)
- using awk program statically-linked on DragonFly host machine (NG)
I made sure that the vkernel and the world are in sync. If you have any
other idea to try, please let me know.
Thanks.
