Description
- Build the attached project with a developer build of Qt:
qt-cmake -S /tmp/report/ && cmake --build . --parallel
- Run the resulting program and pass the attached xml file:
./report 54551.xml
It crashes with a failed assert:
ASSERT: "len >= 0" in file /home/qtrob/dev/g++-12.2.0/qt-6.4.1-nowebengine-devbld/qtbase/include/QtCore/../../../../../src/qt-6.4.1/qtbase/src/corelib/text/qstringview.h, line 146 Aborted (core dumped)
