Hmm, depressing. data structure corruption bugs are always a pain, part
of why I sworn I had coded enough C for one lifetime.
Unfortunately I have the latest mysql-devel-3.23.58-14 that's stable for
fedora, as well as libmysql.so and the sql server is on a different
machine. Everything else is virgin Fedora 3 plus apt-upgrades, and
something in the new Myth brings out this bug where 0.16 didn't with the
same mysql libraries.
Anybody running Myth with the mysql-devel-4 libraries? They are not
official fedora supported but people have built rpms of them.
Any suggestions on things to turn off when building? I have on
xvmc (but disable it in the setup screens), x11, xv, ivtv, alsa, lirc,
opengl and xrandr, but since this is definitely triggered by seek (even
8 second back seek) only xvmc seems like a trigger if it were not disabled.
Sadly, a google for this error with mysql reveals nobody else reporting
such a problem. Is there something I could change the DBType from in
mysql.txt instead of QMYSQL3?
(Un)Fortunately, I can now duplicate the bug in seconds.
Since this particular instance happened when trying to fetch the delinterlace
settings from the database, perhaps I'll play with changing the filter,
but I'm grasping at straws here.
