s .force_encoding 'ascii-8bit'
s1.force_encoding 'ascii-8bit'

r = Regexp.new '[\001\002\003]\000(.*?)\xAA' , nil , 'n'

s .match(r)   #=> #<MatchData "\x01\x00(\t\x00\x04\x02\x00'\xAA" 1:"(\t\x00\x04\x02\x00'">
s1.match(r)   #=> nil  #why?

I think this issue is not a bug.

Because s1 string contains "\n" character, the match fails.
Try with
r = Regexp.new '[\001\002\003]\000(.*?)\xAA' , Regexp::MULTILINE , 'n'

ok, why not set Regexp::MULTILINE by default ?
