Post subject:  Cool VL Viewer 1.30.2.16 on Mac crashed after teleport.
This afternoon I teleported to a destination, and my viewer crashed immediately after I arrived. Cool VL Viewer log and crash dump files attached. The viewer log compressed to larger than 64K so I had to split it.

As you can see from the log, the viewer reports a region crossing time of 42059.5 ms (42 seconds !) when the TP only took 3 seconds... Probably some glitch in the connection to the simulators.

However, the viewer should not have crashed at all.

The crash log clearly shows (*) it happened in LL's Extended Environment code, where pointers are used without being checked for NULL (and one got obviously NULL-ified during the TP glitch). I added NULL checks/guards for next release.

(*) There are not many thing I like with Apple (a total euphemism), but macOS at least produces very detailed and informative crash logs, far better than what Windows or even Linux provide...

Should be fixed in today's release (v1.30.2.18).
