Illustration of the problem with the part of the source code

Another attachment added. Here is a screenshot of the error log. I added a
printf into the source code to verify the problem.

Needless to say, the same executable works on Windows without problems, it also
works flawlessly when its counterpart is compiled for x86-32 and run under
Wine.
