Re: [sr-dev] Segfaults in mem subsystem

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, MAX_URI_SIZE 1024, BUF_SIZE 65535, DEFAULT PKG_SIZE 4MB 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.

() (gdb) info local r = 0x7fa2312af83ca962 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?
