What's different Debug Build and Release Build in Qt?

I developed application with ArcGIS. This application use TCP, and receive data from other PC.

When built with Debug Build and received data, the application terminated abnormally and I got error.

Error statement:

D:\agent\_work\9\s\src\vctools\crt\vcstartup\src\misc\amd64\chkstk.asm:109: Error: Debugger encountered an exception: Exception at 0x7ff63934e988, code: 0xc00000fd: stack_overflow, flags=0x0 (first chance)

After that, I tried to build with Release Build and received data. Strangely enough, it was received without error.

What's the difference between the two? How to avoid errors?

My environment

• OS: Windows10
• QtCreator: 4.14.0_rc1
• Kit: Qt5.15.0 MSVC2019 64bit
• ArcGIS: 100.8
