    Fix read-after-free in matroska_read_seek(). · 33301f00
    Xiaohan Wang authored
    In matroska_read_seek(), |tracks| is assigned at the begining of the function.
    However, functions like matroska_parse_cues() could reallocate the tracks so
    that |tracks| can get invalidated.
    
    This CL assigns |tracks| only before we use it so that it won't be invalidated.
