Just fixed in mythtv-0-21-fixes and trunk.

Yes. It has a lot of static strings in it.
Some of the gcc flags like -fwritable-strings
-fdata-sections may help work around the bug?

I haven't found a clean way to do this yet.


Either change the optimisation for the whole directory:

% svn diff *.pro
Index: libavcodec.pro
===================================================================
--- libavcodec.pro      (revision 16905)

  contains( HAVE_ARMV5TE, yes ) {

  contains( HAVE_ARMV6, yes )      { SOURCES += armv4l/ 
simple_idct_armv6.S }



or make, cut and paste the command that failed,
remove/change the -03, and then run make again.
