I can't see any way you could use compression to crash the process. I did
try this method, but the minute we try to buffer_append() the data to the
output buffer (in buffer_uncompress()), the data we try to append >1mb
therefore buffer_append_space() crashes BEFORE we're actually able to
"allocate" the required space. i.e. it crashes on the wrong fatal() call
for what we want. Therefore we have to somehow allocate <1mb at a time to
successfully overflow. So I don't see quite how we could crash the process
by sending it a compressed 10mb packet or anything.
Any suggestions?
