Description David Kutálek 2012-03-28 15:17:55 UTC
Description of problem:

On one of ours machines, there is big number of segfaults seen in dmesg, like:

ld-linux.so.2[7326]: segfault at 4 ip 0053ba35 sp bfcfd894 error 4 in ld-2.12.so[535000+1e000]
tar[11071]: segfault at 2e2e2e2e ip 0050ea38 sp bf817d8c error 4 in libc-2.12.so[3d9000+189000]
make[15896]: segfault at 0 ip 0805e862 sp bfdda5f0 error 4 in make[8048000+28000]

Big majority of these are about ld-linux.so.2, and all are stating 'error 4' except these two:

npviewer.bin[26200]: segfault at 218 ip 03182496 sp bffa1a78 error 6 in libflashplayer.so[2f04000+bc4000]
dropwatch[29080]: segfault at 13 ip 0017ec93 sp bfd785d8 error 6 in libc-2.12.so[110000+189000]

I had a problem with rebuilding of openjdk src rpm yesterday, it ended with segfaults on various places, and always there was a new dmesg segfault entry after running it.

Version-Release number of selected component (if applicable):

.qa.[root@i386-6c-m1 ~]# uname -a
Linux *** 2.6.32-220.4.2.el6.i686 #1 SMP Mon Feb 6 16:46:31 EST 2012 i686 i686 i386 GNU/Linux
.qa.[root@i386-6c-m1 ~]# rpm -q kernel

.qa.[root@i386-6c-m1 ~]# rpm -q glibc

How reproducible:

Almost always by running complex rpmbuild command for java-1.6.0-openjdk

Steps to Reproduce:
1. rebuilding some openjdk package using rpmbuild --rebuild --target=i686
2. this is seen only on one specific i686 machine
Actual results:

segfaults causing tasks to fail

Expected results:

no segfaults seen

Additional info:

Access to this machine available on request

Comment 11 RHEL Program Management 2012-05-03 05:24:36 UTC
Since RHEL 6.3 External Beta has begun, and this bug remains
unresolved, it has been rejected as it is not proposed as
exception or blocker.

Red Hat invites you to ask your support representative to
propose this request, if appropriate and relevant, in the
next release of Red Hat Enterprise Linux.

Comment 12 Linda Wang 2013-06-20 06:31:47 UTC
Haven't seen any updates from David. so assume the segfault issue
went away. Close for now, please feel free to reopen if the issue
shows up again. many thanks.
