CDB process terminated exceptionally

Tancen

Kits:

The CDB crashed after line 60

But, In the WinDbg, Everything is all right.

How to fix it? Thanks.

Codes:

Since it doesn't seem that you are using Qt at all in your code, what happens if you compile and debug it outside of QtCreator?

@mchinand I tried compiling the source codes in Visual Studio 2019, And running it with debug mode, Step over around line 60, Every thing is OK.
