 I'm running MythTV on a Wandboard (armhf architecture). 0.26 worked fine,
 but after upgrading to 0.27, mythcommflag consistently crashes after a
 varying amount of time, usually a few seconds. I also tried
 v0.28-pre-651-g3d91559 and the bug is present there too:

 $ mythcommflag --chanid 1621 --starttime 20131224000000

 This is running the Ubuntu 13.10 image from
 http://www.armhf.com/index.php/boards/wandboard/ . The crash also happens
 using the Debian Wheezy image from the same page. Apart from mythcommflag,
 all other MythTV functions seem to work normally.

 I'm attaching output from gdb and valgrind.
