Subject: segfault in "blkparse -s"?
Date: Sun, 18 May 2008 02:54:53 +0000 [thread overview]
Message-ID: <482F9A7D.3060001@cesmail.net> (raw)
Environment: Gentoo Linux 2.6.25 kernel, AMD Athlon64 X2 dual core, 4 GB
of RAM, single disk drive sda, reiserfs filesystems.
I started up blktrace with "blktrace -d /dev/sda". Version is
$ blktrace -V
blktrace version 0.99.3
Then I recompiled php to generate some I/O. Then I stopped blktrace and
ran blkparse. Version is
$ blkparse -V
blkparse version 0.99.3
Both "blkparse sda" and "blkparse -t sda" run fine, but "blkparse -s
sda" segfaults:
$ blkparse -s sda > blkparse.out
Segmentation fault
It generates partial output before crashing.
I'm planning to try this again under gdb to get a traceback. The Gentoo
"btrace" package is sys-block/btrace-0.0.20071210202527 -- if this is
too old, let me know and I'll install something more recent from the
repositories.
