Package: linphone
Version: 3.6.1-2.3
Severity: minor
Usertags: goto-cc
During a rebuild of all Debian packages in a clean sid chroot (using cowbuilder
and pbuilder) the build failed with the following error. Please note that we
use our research compiler tool-chain (using tools from the cbmc package), which
permits extended reporting on type inconsistencies at link time.

The difference here lies in the type of the rem_addr member, with the full
declaration to be reviewed here:
http://sources.debian.net/src/linphone/3.6.1-2.3/oRTP/include/ortp/rtpsession.h?hl=116#L116
Note that this will affect the offsets of various further members, making the
two types inconsistent in several ways. Yet this might all be safe at present as
commands.c, at least on a quick review, does not appear to access any of the
members. As such it may be desirable to keep the structure private rather than
exposing it via the header file.
Best,
Michael
