 In couple of days old master, libavutils/log.c av_vlog() function
 sometimes crashes on line:

 482     if (avc && avc->version >= (50 << 16 | 15 << 8 | 2) &&

 I'm using ffmpeg libs in my Android app and get this kind of dump:

 ********** Crash dump: **********

 av_vlog

 I don't know how to produce backtrace.  I don't get the crash if I comment
 out the if statement.
