i tried to start sip router without loading my local module. crash
still happens at the same point as before, i.e., when sip router tries to
compile modparam that contains a regular expression:
modparam("auth_db|dialplan|domain|htable|lcr|msilo|mtree|permissions|usrloc",
"db_url", "MYSQL_SIP_PROXY_URL")
(gdb) where

i think regcomp.c is part of c library in debian squeeze.
