Simulation crashing when having a static gate in Gate Control List

[paintspot87]

Hi,

I'm running omnet 6.0.2 and INET 4.5.2 and have pulled fixes from the master so hasGcl = true works.

But when modifying a simple showcase such as inet\showcases\tsn\trafficshaping\timeawareshaper

With the following configuration then we get the error: <!> (omnetpp::cValueArray): get(): index 0 is out of bounds. Where index depends on which gateState is left unchanged in *.switch.eth[*].macLayer.queue.gateControlList.gateStates = ["10000000", "01111110"]

I think you should be able to define 8 queues but don't necessarily ever open or close some of them. They should be able to be in one state indefinitely. But omnet crashes when I try to do this. I have generated states from a TSN scheduler and some queues are always open or closed in my case.

Thanks for reporting this issue. I'll check this soon.

This issue has been fixed in the INET master branch just now. Please check if it work for you.

Thank you for being so incredibly fast @levy, it seems to be working now. Much appreciated!
