 I got at an almost stable Gentoo with gcc 4.4.5 :

 * QA Notice: The following files contain runtime text relocations
  *  Text relocations force the dynamic linker to perform extra
  *  work at startup, waste system resources, and may pose a security
  *  risk.  On some architectures, the code may not even function
  *  properly, if at all.
  *  For more information, see http://hardened.gentoo.org/pic-fix-guide.xml
  *  Please include the following list of files in your report:
  * TEXTREL usr/lib/libavutil.so.50.43.0
  * TEXTREL usr/lib/libpostproc.so.51.2.0
  * TEXTREL usr/lib/libavdevice.so.52.5.0
  * TEXTREL usr/lib/libswscale.so.0.14.1
  * TEXTREL usr/lib/libavformat.so.52.110.0
  * TEXTREL usr/lib/libavfilter.so.1.80.0
  * TEXTREL usr/lib/libavcodec.so.52.122.0

  *            fine but exhibit random runtime failures.

  * libavfilter/libmpcodecs/vf_spp.c:301: warning: dereferencing pointer

  * Please do not file a Gentoo bug and instead report the above QA
  * issues directly to the upstream developers of this software.
