Ok. So it is not a HttpState but a buffer for HTTP headers. Gives
three options:

a: The pointer was corrupted in comm (not very likely)

b: The HttpState has been freed and reused as something else. Adding
cbdata fences to comm would eleminate any such risk.

c: Something processing headers has a serious buffer overflow (not
very likely).
