    I see.  So, regex_compile should check the size of offset
    before storing it in a buffer for compiled code.  But,
    doesn't it mean that if regex_compile does that check, we
    don't have to have the limit of 2^16 as below?

regex_compile is the place that checks, and I am going to cut the
value of MAX_BUF_SIZE by 50%.
