Rewrite: fixed segfault with rewritten URI and "alias". The "alias" directive cannot be used in the same location where URI was rewritten. This has been detected in the "rewrite ... break" case, but not when the standalone "break" directive was used. This change also fixes proxy_pass with URI component in a similar case: location /aaa/ { rewrite ^ /xxx/yyy; break; proxy_pass http://localhost:8080/bbb/; } Previously, the "/bbb/yyy" would be sent to a backend instead of "/xxx/yyy". And if location's prefix was longer than the rewritten URI, a segmentation fault might occur.
