Subject: Valgrind profiling results gone bad
Hi,
I just re-ran my ”standard file” for profiling and the results differs significantly:
tools/valgrind-wireshark.sh -p -Y -b /home/ericsson/wireshark/ /home/ericsson/etxrab/TCT_SIP_traffic.pcapng
==13803== Callgrind, a call-graph generating cache profiler

==13803== Using Valgrind-3.10.0.SVN and LibVEX; rerun with -h for copyright info
==13803== Command: /home/ericsson/wireshark/.libs/lt-tshark -Y frame -nr /home/ericsson/etxrab/TCT_SIP_traffic.pcapng
==13803==
==13803== For interactive control, run 'callgrind_control -h'.

The culprit seems to be proto_tre_add_item() does any one know what changed? and why?
