Re: [gamin] Re: Building gamin 0.1.6

[Mark Carey <mark carey gmail com>]

Ok so I have rebuilt gamin with debug support and poll, dnotify and inotify
backends.

Following the instructions at http://www.gnome.org/~veillard/gamin/debug.html my
system does not have a gamin_client program so I am not quite sure what to do,
but I tried the following.

Terminal 1 started,

$ export GAM_DEBUG=
$ /opt/gnome2.12.1/libexec/gam_server --notimeout test \
  > gamin-server-output.log 2>&1
*** glibc detected *** double free or corruption (fasttop): 0x0807c778 ***
Aborted

Note here that the message from glibc is not immediate it only ocurrs after we
manage to capture the contents listed below.
(http://homepages.paradise.net.nz/markcare/linux/gamin/1/gamin-server-output.log)

In Terminal 2,

$ export GAM_DEBUG=
$ export GAM_CLIENT_ID=test
$ startx > x-gam-debug.log 2>&1

Atttached complete contents of gamin-server-output.log

As indicated previously I have instrumented gam_data.c with the previously
mentioned patch I can change the error to be.

invalid length 10794 expected sizeof(GAMPacket) 4106 got 10794
invalid length 10794 expected sizeof(GAMPacket) 4106 got 10794

My c experience tells me that sizeof is a compile time operator.  How do I find
who is sending GAMPackets that are close to three times the size that they
should be?

Is this any help?  If not please advise what further I need to do to
produce useful output.
