768	String garbling when using nested regex locations	launchpad.net/~blubberdiblub		"In certain circumstances with certain configurations (I'm not sure about the exact conditions), the string passed as SCRIPT_NAME to phm-fpm gets garbled (it may have been garbled earlier, tho, for instance during fastcgi_split_path_info or during assignment to the fastcgi_param).

We used to have this problem with an earlier version, too (1.4.1 or 1.6.3, I don't remember), in a different config file, which we rewrote (and which is now uglier).

Now it showed up in this config file which I present an excerpt of here when we upgraded from 1.6.3 to 1.8.0.

In the fastcgi hexdump note the variable SCRIPT_NAME, which gets a value of `^/pm/recommended/index.php` assigned by nginx. However, the expected value is `/recommended/index.php`. It appears as if nginx mixed one of the regexes with the path to be parsed.

The request for which that happened was `GET /pma/recommended/ HTTP/1.0`.
