Yep. .ttp -> tw-call.app -> toswin2.app

You must try it without fVDI / NVDI to see memory violation. If you try it
with fVDI/NVDI, you'll get "only" corrupted window. With my fix
(tw-call.app calls toswin2.app with wiscr = 0 in shel_write()) you'll get
no such behaviour.

It's because toswin2.app thinks there are some command line arguments
whereas there are not. So you see, it's quite a dangerous bug, you can't
blame solely the caller for that.
