Add OSG 3.6 binaries to CI script

[ananace]

Will have to drop Visual Studio 2013 support for this, don't have the ability to build up new 2013 binaries for 3.6.

Because of this, #1714 is probably going to be required to switch the CI from VS2013 + VS2015 to VS2015 + VS2017

[ananace]

This should probably not be merged before it's been tested - and verified - by at least two people, seeing as OSG is a rather vital component of OpenMW.

[AnyOldName3]

It no worky.

The file isn't in the archive, so obviously isn't in the extracted version of the archive, either. It was included in previous versions, though.

[ananace]

Right, the new OSG deps don't actually have any zlib DLL, the compression's statically linked.

Or, alternatively, I've just forgotten to copy them over into the OSG packages... oops.

[ananace]

I've uploaded new packages with the missing DLLs now

[AnyOldName3]

I'm building it now. I guess it'll be about 40 minutes until I can tell you if it works.

[AnyOldName3]

It built and runs.

[psi29a]

@AnyOldName3 runs is good, did you run/fly around the landmass to see if there were any crashes with all the loading and unloading of cells (actors and statics)? That is a good stress test.

[AnyOldName3]

I had one crash nearly immediately but can't replicate it with ten other runs doing the exact same thing.

[akortunov]

Not sure if it is a 3.6-specific, but sometimes I get the crash in SceneManager::createInstance().
Log complains about dynamic casts here.

[AnyOldName3]

I don't understand how those dynamic casts could break. The results are being checked before being used.

[akortunov]

I don't understand how those dynamic casts could break.

I even more do not understand.
crash.log

OpenMW can crash randomly in very rare case upon save load or cell change.

This part is common in all cases:

I had one crash nearly immediately

What crash.log says?

[akortunov]

OpenMW can crash randomly in very rare case upon save load or cell change.

I encountered this crash on 3.4.1 too, so it is not 3.6-specific. Weird.

[akortunov]

This PR is very outdated, and we are not going to use 3.6.x by default soon anyway because of its bug. So I see no point to keep this PR opened.
