Subject: Automount segfaults in do_mount_indirect
Date: Tue, 20 Feb 2007 16:05:15 +0100 [thread overview]
Message-ID: <45DB0E2B.5030302@control.lth.se> (raw)

On Fedora Core 6 (autofs-5.0.1-0.rc3.21) I get occasional segfaults in
do_mount_indirect, the issue seems to remain in 5.0.1 version. The attached
patch seems to take care of the issue.
