I seem to have obtained a modest back trace when
ogg123 encountered a segmentation fault.

It is

    Program received signal SIGSEGV, Segmentation fault.
    [Switching to Thread 0xb79da6d0 (LWP 6358)]
    0xb7d25aae in realloc () from /lib/i686/cmov/libc.so.6

    Backtrace stopped: frame did not save the PC

/lib/i686/cmov/libc.so.6 is from version 2.7-18 of libc6-i686, and
/usr/lib/libao.so.2 is from version 0.8.8-4 of
libao2.

For what it's worth, this bug seems to me to
resemble the one reported at
