The following reply was made to PR bin/25361; it has been noted by GNATS. From: Matthew Jacob <mjacob@feral.com> To: Christian Weisgerber <naddy@mips.inka.de>, Andrew Gallatin <gallatin@cs.duke.edu> Cc: FreeBSD-gnats-submit@FreeBSD.ORG Subject: Re: bin/25361: dump(8) command segfaults Date: Mon, 5 Mar 2001 13:33:56 -0800 (PST) Both the -stable and -current with kernels and userland later than February 26 do not show this problem. A -current with a userland of 2/13 and a kernel from yesterday shows this problem. I believe the problem has been addressed, but I'll reconfirm tonite after a buildworld. -matt > > >Number: 25361 > >Category: bin > >Synopsis: dump(8) command segfaults > >Confidential: no > >Severity: serious > >Priority: medium > >Responsible: freebsd-bugs > >State: open > >Quarter: > >Keywords: > >Date-Required: > >Class: sw-bug > >Submitter-Id: current-users > >Arrival-Date: Sun Feb 25 12:40:00 PST 2001 > >Closed-Date: > >Last-Modified: > >Originator: Christian Weisgerber > >Release: FreeBSD 5.0-CURRENT alpha > >Organization: > >Environment: > System: FreeBSD kemoauc.mips.inka.de 5.0-CURRENT FreeBSD 5.0-CURRENT #4: Sat Feb 24 14:37:31 CET 2001 naddy@kemoauc.mips.inka.de:/usr/src/sys/compile/KEMOAUC alpha > > >Description: > > The dump(8) command segfaults: > > $ dump 0af /dev/null / > DUMP: Date of this level 0 dump: Sun Feb 25 20:44:21 2001 > DUMP: Date of last level 0 dump: the epoch > DUMP: Dumping /dev/da0a (/) to /dev/null > DUMP: mapping (Pass I) [regular files] > DUMP: mapping (Pass II) [directories] > DUMP: estimated 67655 tape blocks. > DUMP: dumping (Pass III) [directories] > DUMP: dumping (Pass IV) [regular files] > DUMP: SIGSEGV: ABORTING! > DUMP: SIGSEGV: ABORTING! > DUMP: SIGSEGV: ABORTING! > DUMP: SIGSEGV: ABORTING! > DUMP: SIGSEGV: ABORTING! > Segmentation fault (core dumped) > > dump was working fine in -current as of Dec 25.
