nginx 0.1.35
*) Feature: the "working_directory" directive.
*) Feature: the "port_in_redirect" directive.
*) Bugfix: the segmentation fault was occurred if the backend response
header was in several packets; bug appeared in 0.1.29.
*) Bugfix: if more than 10 servers were configured or some server did
not use the "listen" directive, then the segmentation fault was
occurred on the start.
*) Bugfix: the segmentation fault might occur if the response was
bigger than the temporary file.
