From Randy Terbush <ra...@zyzzyva.com>
Subject New bug?
Date Tue, 18 Jun 1996 16:50:59 GMT
I'm stumped and am hoping that someone else may have some feedback here.

I have a module that is setting r->handler to another module and then
calling run_sub_req(r). I am then getting a SEGV in the SET_BYTES_SENT
macro being called from finalize_sub_req_protocol(). The backtrace
below shows that sub->main->bytes_sent cannot be accessed. I can't
quite figure out if something hasn't been initialized properly or what.
This is being called from mod_include where several sub_requests have
already been run.

#define SET_BYTES_SENT(r) \
  do { if (r->sent_bodyct) \
	  bgetopt (r->connection->client, BO_BYTECT, &r->bytes_sent); \
  } while (0)

void finalize_sub_req_protocol (request_rec *sub)
{
    SET_BYTES_SENT (sub->main);
} 


Breakpoint 2, finalize_sub_req_protocol (sub=0x176518) at http_protocol.c:526
526         SET_BYTES_SENT (sub->main);
