[sr-dev] Segfaults in mem subsystem

[Николай]

Hi *,

we are using kamailio built from source (with minor changes not in mem
subsystem):

# /usr/local/sbin/kamailio -V
version: kamailio 3.4.0-dev6 (x86_64/linux) cd2b26-dirty
flags: STATS: Off, USE_IPV6, USE_TCP, USE_TLS, TLS_HOOKS, USE_RAW_SOCKS,
DISABLE_NAGLE, USE_MCAST, DNS_IP_HACK, SHM_MEM, SHM_MMAP, PKG_MALLOC,
USE_FUTEX, FAST_LOCK-ADAPTIVE_WAIT, USE_DNS_CACHE, USE_DNS_FAILOVER,
USE_NAPTR, USE_DST_BLACKLIST, HAVE_RESOLV_RES
ADAPTIVE_WAIT_LOOPS=1024, MAX_RECV_BUFFER_SIZE 262144, MAX_LISTEN 16,

poll method support: poll, epoll_lt, epoll_et, sigio_rt, select.
id: cd2b26 -dirty
compiled on 17:41:52 Jan  6 2013 with gcc 4.6.3


and facing segfaults in memory control subsystem in different places.
Some examples follow:

Are the issues already known/fixed? Should I post a bugreport?
The memory subsystem looks pretty buggy... Does kamailio implement/use
its own mem allocating system?

PS I'm new to the list - sorry for possibly bad email

Thanks
