Hi Developers, The attached ~30KB large pcap file has 1 NR RRC packet and the current latest official WS version 4.4.7 can decode it properly. This is good.
However, when I try to open and decode it with the latest development
version, it fails (Version 4.5.0 (6f13ac41b7df)).
(I just refetched the whole source code and recompiled again from scratch).
*CLI*:

It seems whatever changes could have been done in packet-nr-rrc.c (or
somewhere else?) it did heavily impact the start_idle_count (or when it's
reset) and the "*PROTO_TREE_MAX_IDLE* *50000*" in proto.c is not enough
anymore.
I was testing with higher values and ended up with "*PROTO_TREE_MAX_IDLE*
*93100*" to make it work and be able to decode the packet (93000 still
failed).
That is a significant issue, I believe.
Could anyone please have a look at what could be the underlying issue?
Thank you.
Regards,
Tamas
