[SR-Users] set_body_multipart and memory leak

I found root cause of the second issue.
after converting body to multipart
in msg_translator.c function "check_boundaries" see that flag
FL_BODY_MULTIPART is set , executing "build_body" function which
returns buffer
but function "get_boundary" called at line 1752 of msg_translator.c (
if(get_boundary(msg, &ob)!=0) return -1;) find that content type of
message not multipart/mixed but application/sdp and returns -1
then exit from function "int check_boundaries(struct sip_msg *msg,
struct dest_info *send_info)" is performed without feeing buffer.
I have changed line 1752 of msg_translator.c
from
if(get_boundary(msg, &ob)!=0) return -1;
to
if(get_boundary(msg, &ob)!=0) {
if(tmp.s) pkg_free(tmp.s);
return -1;
}
And 3-rd, last for my case, memory leak has gone away.
I does not know why check "if(!(msg->msg_flags&FL_BODY_MULTIPART))"
returns false...
But in this way it works for me without memory leak.
