Description (Last modified by jan)

When I try and do something like the following: 

url.rewrite-once = (    
    "^(/css/.*)$" => "/media/%0$1"    
)

Then lighttpd segfaults. If I replace %0 with something hardcoded, then it works fine.

I'm using lighttpd version 1.4.11-3ubuntu3 on ubuntu dapper amd64. I tried the 32bit version in a chroot and got the same thing. I checked out the latest code and tried to compile it manually, but got a compile error. Then I checked out revision 1116 because it looked like that was a checkin that fixed a problem that I thought might be the same thing and compiled it, but it gave the same error.

Attached, please find my lighttpd configuration, gdb output and valgrind output

ok.. just changed the following: 

url.rewrite-once = (
        "^/((files|css|images|js|flash|cache)/.*)$" => "/media/%0/$1",
        "^(.*)$" => "/main.fcgi$1",
    )

to: 

$HTTP["host"] =~ ".*" {
    url.rewrite-once = (
        "^/((files|css|images|js|flash|cache)/.*)$" => "/media/%0/$1",
        "^(.*)$" => "/main.fcgi$1",
    )
}

and now it works. In my opinion it should still not have crashed, though ;)
