Hint: Pay close attention to the second sentence of the microproject
you've undertaken:
Rewrite bulk-checkin.c:finish_bulk_checkin() to use a strbuf for
handling packname, and explain why this is useful. Also check if
the first argument of pack-write.c:finish_tmp_packfile() can be
made const.
It's the clue to understanding the crash.
