Description
I was trying to use a QDoubleSpinBox in my project, and always got an assert on startup.
- Launch the repro application
- EXPECTED: The application runs and shows QDoubleSpinBox with default properties
- ACTUAL: The application terminates with an assert
Assert message from debug build:
Program: D:\Programs\Qt\6.2.0\msvc2019_64\bin\Qt6Cored.dll Module: 6.2.0 File: C:\Users\qt\work\qt\qtbase\include\QtCore\../../src/corelib/text/qstring.h Line: 1210 ASSERT: "size_t(i) < size_t(size())" in file C:\Users\qt\work\qt\qtbase\include\QtCore\../../src/corelib/text/qstring.h, line 1210
