regular expression error in 3.0.x not present in 3.0.6

[Aaron Hurt]

I have a policy.d file containing a regular expression that works in 3.0.6 that I’ve tried with two different flavors.
Both flavors load and work in 3.0.6 but error in the latest 3.0.x branch.

Flavor1:
simple_nt_regexp = "^([^\\\\]*)(\\\\(.*))$"

Flavor2:
simple_nt_regexp = "^([^\\\\]*)\\\\(.*)$”


In 3.0.x from today:

/opt/local/etc/raddb/policy.d/strip-user-domain[9]: Invalid regular expression:
/opt/local/etc/raddb/policy.d/strip-user-domain[9]: ^([^\\]*)\\(.*)$
/opt/local/etc/raddb/policy.d/strip-user-domain[9]: ^ Pattern study failed: unknown or incorrect option bit(s) set

/opt/local/etc/raddb/policy.d/strip-user-domain[10]: Invalid regular expression:
/opt/local/etc/raddb/policy.d/strip-user-domain[10]: ^([^\\]*)(\\(.*))$
/opt/local/etc/raddb/policy.d/strip-user-domain[10]: ^ Pattern study failed: unknown or incorrect option bit(s) set

Is there something obvious that I am missing?
