Comment (by phk):

I can make neither heads nor tails of this backtrace.

There is no way to get from HTTP1_Session() to ses_handle() - which is
only called from the waiter (in Wait_Call()) and unless the compiler is
positively psychic no optimization can get that far.

Something is horribly hosed here, an I have no idea what it is.

Unless new evidence emerges, this ticket will time out as "not actionable"
around X-mas.
