[sr-dev] assign 'null' value to pv not work

Hi all, for deleting a pseudo-variable we use in kamailio time the 'null' assignment. This is needed for example when you use the hash table or memcache module. I think it worked some time ago, but now it seems broken. From a test cfg: ... 44: $mct(test) = null; ... Oct 8 15:07:20 ca ser: : <core> [cfg.y:3209]: parse error in config file sip- router/test/unit/45.cfg, line 44, column 19: syntax error Oct 8 15:07:20 ca ser: : <core> [cfg.y:3209]: parse error in config file sip- router/test/unit/45.cfg, line 44, column 19: '('')' expected (functioncall) Is this a known problem, perhaps i forgot about some compatibility workaround?
