This tree is for reproducing http://subversion.tigris.org/issues/show_bug.cgi?id=1421 The reproduction data was constructed using bits of the xiph.org repository, supplied by Jack Moffitt . The problem has to do with the creation of branch 'volsung_20010721', parts of which are copied from trunk, and other parts from branch 'xiphophorus': src/ao_private.h,v: volsung_20010721 ==> 1.1.0.2 src/audio_out.c,v: volsung_20010721 ==> 1.15.0.2 xiphophorus ==> 1.1.1 src/COPYING,v volsung_20010721 ==> 1.1.1.1.0.4 xiphophorus ==> 1.1.1 (These are actually from /ao/src/ in the xiphrepo; note that COPYING,v is actually /ao/COPYING,v in the original data, I just moved it to make the reproduction simpler.) See the issue for more details.
