Some bug in Lazarus or Qt5 ws.
a) Laz release 2.0.8. CudaText starts and works ok (Laz cannot
render monospaced fonts as monospaced, and some labels are cropped
b) Laz trunk 2.1. CudaText shows AV on start (after showing
form, it works then). Monospaced fonts - fixed, labels cropped -
Haiku has GDB 6.x and cannot debug the AV (debug error). I wrote
the request for new GDB there.
