Changes with nginx 0.5.36 04 May 2008

    *) Bugfix: the "sub_filter" directive might set text to change into
       output.

    *) Bugfix: a segmentation fault occurred in worker process, if empty
       stub block was used second time in SSI.

    *) Bugfix: the "proxy_store" and "fastcgi_store" directives did not
       check a response length.

    *) Bugfix: nginx issued the bogus error message "SSL_shutdown() failed
       (SSL: )"; bug appeared in 0.5.35.

    *) Bugfix: in HTTPS mode requests might fail with the "bad write retry"
       error; bug appeared in 0.5.35.

    *) Bugfix: the "fastcgi_catch_stderr" directive did return error code;
       now it returns 502 code, that can be rerouted to a next server using
       the "fastcgi_next_upstream invalid_header" directive.

    *) Bugfix: a segmentation fault occurred in master process if the
       "fastcgi_catch_stderr" directive was used; bug appeared in
       0.5.32.
       Thanks to Manlio Perillo.
