I've now committed a proper fix to this problem to CVS (will be in 2.3.3
release). Now the parsing buffer is dynamically grown if more space is
needed for parsing. This should cover even extreme cases. There's still a
hard upper-limit (2^16 atm) to prevent misbehaving clients from consuming
massive amounts of memory, but no real-life client should ever hit this
limit.
Thanks for the bugreport! I'll add your name to the 2.3.3 announcement.
