Bug 127266 – app-shells/bash-3.0-r12 broken pipe problem

• Status: RESOLVED WORKSFORME
• Product: Gentoo Linux

[Description Magnus Damm 2006-03-22 22:52:35 UTC]

app-shells/bash-3.0-r12 _sometimes_ returns "broken pipe" with a certain script.

Failing gentoo box with app-shells/bash-3.0-r12:
damm@cherry ~ $ ./bug.sh
./bug.sh: line 4: 16714 Done                    grep "^||$port||"
     16716                       | cut -c 6-
     16717                       | tr "|" "\n"
     16718 Broken pipe             | while read line; do
    echo line=$line;

The same script never seems to fail on this debian box:

Created attachment 82919 [details]
testcase that sometimes trigger

[Comment 2 SpanKY 2006-03-23 06:19:55 UTC]

try bash-3.0-r14

[Comment 3 Magnus Damm 2006-03-23 18:01:29 UTC]

Thanks, but it does not help.

I can still trigger the bug with bash-3.0-r14.

Is someone else able to trigger it? Or is it only me?

Maybe this problem is related to some library instead?

[Comment 4 SpanKY 2006-04-10 22:03:10 UTC]

ok, bash-3.0 reproducibly barfs on your bug.sh for me

however, bash-3.1 works fine, so that's good enough for me ;)
