Hi,
On a Gentoo Linux system I'm getting the following compile-time warnings (kamailio-3.3.1 ebuild):
* python_msgobj.c:529:5: warning: dereferencing type-punned pointer will break strict-aliasing rules
* ld_con.c:241:4: warning: implicit declaration of function 'ldap_simple_bind_s'
* perl.c:340:2: warning: null argument where non-null required (argument 2) * perl.c:340:2: warning: null argument where non-null required (argument 1)
Hopefully I can just ignore these messages.
Thanks,
Vieri

Hello,
Can you provide more information about what compiler (name, version) are you using?

Same warning here with gcc v4.4.7 in Gentoo too.

Commit 1abde923ee3cbdcce69b72d223fb0c487b892b6e by Daniel seem to not fix the warning.
I know QA Gentoo complains about it, may exhibit random runtime failures. We can live with it :) just a compiler warning. It compiles fine. (it's a matter of disabling strict_aliasing in Makefile (-O2 implies -fstrict-aliasing)).
