wine log

I have one test program (pomocni-llvm-mingw.exe) who acts very strangely in
wine git version(Wine-6.7-175-G2Deb8C2825A) while in the Windows10 does not
work at all.

What the most surprise is that although the wine64 call is terminated for the
specified program, wine processes and the program itself remain in memory and
after interruptions:

root      422318    1456  0 06:38 pts/16   00:00:00 grep win

The program is made with the latest version of llvm-mingw:Clang Version 11.0.0
(https://github.com/llvm/llvm-project.git
176249bd6732a8044d457092ed922768724a6f06).

That same program when it is made and performed in Linux works correctly as
predicted.

In the attachment, I send the following files:

1. wine log - pomocni-cross-mingw64.log

2. exe characteristics - trt.log

3. test script - pomocni-cross-mingw64.sh

4. test program - testIsppRadenik.cpp
