No idea how it can crash there. av_log_set_callback() just sets a static
variable to the callback that was passed as parameter.

There must be something else really broken :)

Could you check if a program that just calls av_log_set_callback() with
some function as parameter crashes too?

And does something like valgrind exist for mips? Might help here :)
