I was going to post, or rather forward, Christian's explanation to the
vorbis-tools 1.2.0 thread.  Might as well do it here:

"ogg123 suffers from a 32/64-bit screwup on LP64 platforms.
cfgfile_options.c expects opt_type_bool and opt_type_int settings
to be stored in long int variables.  However, ogg123.c:fileopts[]
points to options.shuffle and options.repeat that are defined as
int in ogg123.h.  This causes 64-bit writes to 32-bit variables.
Depending on endianness, strict alignment requirements, and luck,
this can result in garbage or address errors.  (E.g., on sparc64,
ogg123 immediately dumps core.)  The easiest way to fix this is to
bump options.shuffle and .repeat to type long int."
