The default handler always calls ap_discard_request_body, even for
GET requests, which is perfectly normal.  I assume you're also
using mod_apreq (otherwise your post doesn't belong on this list).
Any input filters upstream of mod_apreq's filter may get carried 
onto the subrequest's filter chain, depending on how mod_apreq is 

Some combination of the above facts is probably what's causing your 
filter to occasionally segfault.
