--- Comment #5 from Anastasius Focht focht@gmx.net 2013-12-01 11:18:19 CST --- Hello Dmitry,
--- quote --- BaseCamp.exe and its dlls don't even import that symbol. Probably the actual call is made by some .net component? --- quote ---
running this thing under managed debugger yields the following before the crash:

The .NET Framework libs just pass the region data to gdiplus. The main assembly 'BaseCamp.exe' (32 MiB) refuses to load in ILSpy but fortunately some free old (pre-commercial) .NET Reflector 6 version can decompile it.
Looks like C++/CLI code compiled to CLR bytecode. I'll attach a snippet of the code that is used to create the region data.
Regards
