When I try to debug code and when there is breakpoint I get a window:
The inferior stopped because it received a signal from the operating system.
Signal name: ?
Signal meaning: Unknown signal
Screenshot:
Also, I get issue:
:-1: error: An exception was triggered: 
Exception at 0x4015f6, code: 0x4000001f: Win32 x86 emulation subsystem breakpoint hit, flags=0x0.
Screenshot:
Also some screenshot:
Building and running code gives me no error.  I have read this but I have no antivirus other than Windows Defender and I disabled it real-time protection. I use Windows 8.1
I also use QT, mingw and gdb from msys2.
Question: What is the problem and how to solve it?
                Please post all relevant error messages as text.  Pictures of exceptions are insufficient.

                @fuzI have added debugger logs. Is there any information that you think  I can post as text to improve my question?

                All the information is important, especially the exact text of the error messages so other people can search for them.  Please do not post Paste Bin links, doing so is frowned upon on Stack Overflow.  Instead, post the debug logs inline into your questions.

                @fuz You are right posting everything as text here will improving search. I posted first log as a text but when tried to post the second log too I exceeded max char limit. What should I do? Post error messages as text here and logs at pastebin or there is any better way?

                I am not sure.  Try to post in your post what is most relevant, the other stuff can be left out unless requested specifically.

I was using qtcreator 64 bit but for the project selected kit mingw-w64 32 bit. I think that difference in bitness caused error.
Now when I use qtcreator 64 bit with kit mingw-w64 64 bit, debugger works fine
I got by help from Reddit user jedwardsol:
4000001f is coming from the x86 emulation layer of 64-bit Windows. Perhaps your debugger doesn't understand it.
Try building a 64-bit program instead.
