Comment (by mike.desimone@…):

 Having this exact problem with these Gentoo builds of MythTV:

 * 0.27.5_p20150627
 * 0.27.5_p20150904-r1
 * 0.27.5_p20150904-r2

 Gentoo's gcc 4.9.3. CFLAGS="-march=amdfam10 -O2 -pipe". Here's the link
 command and its output:

 Installed MythTV is 0.27_p20140321, and was probably built before the
 compiler was upgraded to the 4.9 series.

 Going to attempt a patch.
