I tried at first to set up a script which creates files with random data of
increasing length to generate a smaller testcase, but the script ran very slow
(mainly because of /dev/random taking long to generate random data). I am also
not sure how the bzip2 algorithm behaves on pseudorandom data and if the error
will be triggered at all.

I think that to create a testcase, knowledge of the algorithms used is needed to
generate testcases for the boundary conditions; in other words you already need
to have a good idea what the error might be to write a testcase for it (and I
have no understanding of how bzip2 works).
