vorbiscomment gives a SIGSEGV (segmentation fault) with --tag
I expected --tag to work exactly like -t. Instead, it causes a segfault whenever it appears in the command line.
[from SVN checkout of R15399] ~/src/vorbis-tools/vorbiscomment$ ./vorbiscomment --version vorbiscomment from vorbis-tools 1.3.0 ~/src/vorbis-tools/vorbiscomment$ ./vorbiscomment --tag Segmentation fault ~/src/vorbis-tools/vorbiscomment$ ./vorbiscomment -t ./vorbiscomment: option requires an argument -- t vorbiscomment from vorbis-tools 1.3.0 by the Xiph.Org Foundation (http://www.xiph.org/) <snip usage>
I realize it's incorrect to call --tag with no arguments, but the bug manifests with or without an argument. It appears to be somewhere in the option parsing:

I was able to reproduce this bug with trunk (revision 15399) and 1.2.0. This is on amd64 box running debian testing.
