#2705 SIGSEGV with WS3
Hi,
I get crashes with WS3 around EGPH every time. They happen around 2-3 minutes after switching to WS3, mostly right after one of the fg-typical "stutters". This time I managed to get a backtrace.
I have not much experience in gdb but I'm willing to recreate the bug with some guidance and provide additional info.
Metadata: FG and OSG self-built on debian testing. FG/SG next, OSG 3.6.5-rc3. NVidia GTX 1060
backtrace:

Could you try setting the /scenery/use-vpb=true on the command line?
Support for swapping between WS2.0 and WS3.0 at runtime isn't very good, so it's best to start with WS3.0 if you want to use it.

I've tried that - it also segfaults after a while...
Interestingly this doesn't happen with your new Lelystad scenery, only with the older pack for the UK. If you can give me a newer download for the UK scenery with a checksum I can check for possible corruption...
This issue never again appeared for me since the new Tile Caching went active. I think it can be closed for now.
