[SR-Users] Crash kamailio 4.3.1

[Thibault Gueslin]

Federico,

I have tried to apply your commit on the branch 4.3 (just the modifications
on t_append_branch.c)

The result is not very good (failure route not called, 408 timeout not
send...)

Have you a patch for the 4.3 branch ?

Regards

thibault
