Hello Dmitry,

--- quote ---
BaseCamp.exe and its dlls don't even import
that symbol. Probably the actual call is made by some .net component?

running this thing under managed debugger yields the following before the
crash:

--- snip ---

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
