encoder_example (and libvorbis?) leaks memory in managed bitrate mode
This is in libvorbis 1.0 final. Change vorbis_encode_init_vbr(...., 0.5) to vorbis_encode_init(..., -1, 128000, -1) in encoder_example.c (as described in the comments already in that file) and memory usage grows steadily as data is encoded. Memory usage is constant if _init_vbr() is used instead. Tested on RedHat Linux 7.3, with the gcc version 2.96.
