The test case was pretty simple, but I can't produce the crash and valgrind shows nothing (but that may be because it's broken on OSX 10.8)

	User-Name = "testu"
	Framed-IP-Address = 1.2.3.4
	Acct-Status-Type = Start
(1) # Executing section preacct from file /usr/local/freeradius/etc/raddb/sites-enabled/default
(1)   group preacct {
(1)  - entering group preacct {...}
(1)   [preprocess] = ok
(1)    policy acct_unique {
(1)   - entering policy acct_unique {...}
(1)    ? if ("%{string:Class}" =~ /ai:([0-9a-f]{32})/i)
(1) 	expand: '%{string:Class}' -> ''
(1) ? Evaluating ("%{string:Class}" =~ /ai:([0-9a-f]{32})/i) -> FALSE
(1)    ? if ("%{string:Class}" =~ /ai:([0-9a-f]{32})/i) -> FALSE
(1)     else else {

Brian, could you post the results of running it under valgrind?
