[mythtv-users] Possible root cause for frontend/backend crashes

[Don Bostrom]

Hello,

I'm new to this list, so I appologize in advance if this information is old
news.

I have found that the main cause of MythTV crashing on my system (both the
frontend and the backend) is a seg fault in the MySQL library function
my_strcasecmp_8bit().

After recompiling MythTV with various option combinations and having no luck,
I tried a Google search and found a link to this official MySQL bug report
<http://bugs.mysql.com/bug.php?id=7344>.

It appears this is a known problem in MySQL and is triggered by the specific
usage patterns of the QT library. The problem still exists in version 4.1.10a
of MySQL, but will be fixed in 4.1.11.

I hope this information relieves someone else of the many hours of frustration
that I had while trying to get MythTV up and running for the first time.

Arch Linux 0.7; MythTV 0.17; MySQL 4.1.10a; QT 3.3.4; nVidia FX5200 (S-Video
out); Hauppauge PVR-350
