lots of prepends

Today 85.119.176.0/21 was announced by AS20912 with 177 prepends. I noticed 20912 modulo 256 is 176. AS47868 modulo 256 is 252 which matches this mondays prepend-incident.
So, what router OS will put 20912 into a byte and thus end up with 176 in something like "set as-path prepend last-as <no of prepends>" ? It needs to be fixed.
Has anyone noticed any ill effects with IOS and using "bgp max-as"? Will it just drop any prefixes with long as-paths and no other ill operational effects?
