[sr-dev] git:sr_3.0: core: fix selects in optimized rvalue expressions

Module: sip-router Branch: sr_3.0 Commit: d36e9bfbfda41773973ad1822c5905c0cd4dc71e URL: http://git.sip-router.org/cgi-bin/gitweb.cgi/sip-router/?a=commit;h=d36e9bf… Author: Andrei Pelinescu-Onciul &lt;andrei(a)iptel.org&gt; Committer: Andrei Pelinescu-Onciul &lt;andrei(a)iptel.org&gt; Date: Fri Jun 18 22:22:59 2010 +0200 core: fix selects in optimized rvalue expressions - do not attempt to resolve_select() twice the same select. This happened when a rve containing only a select was optimized, the select moved out of the rve and fix_expr() tried to "fix" the already resolved select later. - changed BUG() messages for failed resolve_select() into ERR().
