As you've noted, this is already fixed in the upstream current version. Rawhide contains a newer upstream version and there will be an RHL9 errata version at some point. You can use the Rawhide version now (if the binary rpm doesn't work for you rpmbuild --rebuild the src.rpm instead). An errata has been issued which should help the problem described in this bug report. This report is therefore being closed with a resolution of ERRATA. For more information on the solution and/or where to find the updated files, please follow the link below. You may reopen this bug report if the solution does not work for you. http://rhn.redhat.com/errata/RHBA-2003-361.html |
From Bugzilla Helper: User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.4b) Gecko/20030618 Mozilla Firebird/0.6 Description of problem: On RH9: /usr/bin/strace -e write=1 /bin/echo strace: invalid descriptor `1' It *should* trace the process and dump output on fd 1 -- but it won't for some reason... Version-Release number of selected component (if applicable): strace-4.4.95-2 How reproducible: Always Steps to Reproduce: 1. run: /usr/bin/strace -e write=1 /bin/echo 2. look at error message Actual Results: strace: invalid descriptor `1' Expected Results: execve("/bin/echo", ["/bin/echo"], [/* 40 vars */]) = 0 uname({sys="Linux", node="merlin", ...}) = 0 etc. etc. etc. Additional info: My LANG is set to "C", all other locale vars are unset, running vanilla 2.4.21 kernel (not the rpm version with NPTL). I'm fully up-to-date with 'updates'. On debian sid: ii strace 4.4.99-1 A system call tracer > /usr/bin/strace -e write=1 /bin/echo execve("/bin/echo", ["/bin/echo"], [/* 40 vars */]) = 0 uname({sys="Linux", node="merlin", ...}) = 0 brk(0) = 0x804b80c .... etc. etc.
