Description Šimon (Simon) Rataj 2022-03-15 19:11:44 UTC

STEPS TO REPRODUCE
1. Build the latest Kate revision (d68b46d608da5ba994c692ce2ccbbc4d4d84dc86 for me; kdesrc-build kate)
2. Run it (kdesrc-run)
3. Turn block selection mode with Ctrl+Shift+B
4. Hold Alt and click beyond the end of line

OBSERVED RESULT
The Kate crashes:
ASSERT: "visibleLine >= 0" in file /home/ratajs/kde/src/ktexteditor/src/buffer/katetextfolding.cpp, line 326

EXPECTED RESULT
Another cursor should be created at the appropriate position.
