nginx 0.5.36
*) 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.
