Details

Although there are two PoC files, and they will crash on different location, the root cause should be the same.

For both of the PoCs, when the program tries to divide with tile_width_sb or widest_tile_sb, they are zeros, thus program receives SIGFPE.

The root cause is that mi_cols equals to zero, which makes sb_cols equals to zero, finally makes tile_width_sb and widest_tile_sb equal to zero.
