One example is 'realplay':
[nito@fulgore:~]$ rpm -q RealPlayer
RealPlayer-8.0-1
[nito@fulgore:~]$
With libsafe installed it segfaults, when I remove the libsafe package it works
fine.
Another example is 'mpg123' it segfaults with some (mostly mp3's created with
gnapster) mp3 files that play fine in xmms; oddly enough, if I append a null to
the file by doing 'echo '\0' >> file.mp3' it plays nice. This should give some
clue as to where the problem lies, however I don't have enough time to debug
this. As with 'realplay', the problem disappear when I remove libsafe.
Here is the output of gdb for 'realplay':
