By checking the commits of Drupal 7, I found that this is caused by a patch which heavily uses FUNCTION and yes D7 uses token_get_all. http://xcache.lighttpd.net/ticket/55 seems related but then again, I have xcache.readonly_protection = Off . I tried to write a reproduce script but so far no success. Also, while it does segfault all the time while trying to install Drupal 7, it's not always the same file being tokenized that causes it to segfault, at least that's what I see in the mysql logfile.

bug was fixed in newer version (1.2.2 and later). upgrade and reproduce it before reopening this bug
