TWINE: Demo crashes on launch

[antoniou79]

The Little Big Adventure that is uploaded on the ScummVM site, crashes on launch.
Link to demo:
​https://downloads.scummvm.org/frs/demos/twine/lba-demo-mult.zip

Detection and adding it to ScummVM seem to work fine.

I tried with a local build of 2.8git on Windows 10 x64, from current master HEAD.

The error that is output on the console window is:

Assertion failed: _pos <= _end, file common/stream.cpp, line 265

I will try debugging with Visual Studio to see if more details come up.
