i wrote a new version of local module (below) that is just a skeleton.
when i start sip router, i get to console:
Not starting sip-proxy: invalid configuration file!
but i don't get anything about what is wrong with it.
gdb shows:

from that i see that the problem is that my new local module does not
have db_url module param, but that does not explain why malloc causes
the crash. this is with export MALLOC_CHECK_=2. if i do not define
MALLOC_CHECK_=2, i still don't get any more stuff to console about the
problem in config.
