[mythtv-users] mythfrontend crash -- "stack smashing detected"

[Mike DeSimone]

Hello!

I've run into a problem recently.  It started with version 0.19 about  
a week ago, and upgrading to 0.20 didn't help.  It goes like this:

vid at toybox ~ $ ps auxw | grep myth

*** stack smashing detected ***: mythfrontend terminated

I've stripped my installation (on Gentoo) down to the basic mythtv  
package with no plugins.  I've even removed the themes and rebuilt  
with only ALSA support; same problem.

I'm wondering how to go about tracking this down.  And before you  
ask, no, I was dumb and forgot to back up the 0.19 database.  I can't  
see anything amiss in the mythbackend logs, but I'm not sure I know  
what to look for.
