Yes, it's not fixed in 3.0.3 (but you if you don't use git directly you
can get newer tarballs from http://sip-router.org/tarballs/sr/ ).
Anyway that patch is not related with that mem. allocation problem.

Could you try compiling from sources, with debugging and memory
debugging enabled?

make cfg mode=debug MEMDBG=1 include_modules="tls db_mysql"
make all
(note that if you want to make install, the default path is under
/usr/local, e.g. /usr/local/sbin/{kamailio,ser} )

Add also to your config:
memlog=1
memdbg=1

After that try again sending the REGISTERs and then please send me the
log (it will be quite big, all memory allocation attempts will be dumped
into it).

If by sip-router you mean sip-router 3.0, then it has exactly the same
features as kamailio 3.0 (only some defaults and minor stuff are
changed).
If you mean sip-router 3.0.99 or 3.1, then it should have more features
then kamailio 3.0 (being the newer soon to be release).
Note that in 3.1 the tls module was mostly re-written (to support async
mode) and some module parameters which had equivalents in the tcp config
options were removed. Are these your missing features?
