Hello All, To have a useful trace, I had to build (and install) gambas3 and glibc locally with debug symbols.
Binaries still are 'optimized' a bit, however. Here follows how I got the crash (SIGSEGV) : Under Bash : valentin@valentin-SATELLITE-L875-10G:~$ gambas3 gb.gui: warning: 'gb.qt4' component not found, using 'gb.qt5' instead appmenu-qt: handleReparent 143 The given QMenuBar is already registered by appmenu-qt5, skipping appmenu-qt: handleReparent 143 The given QMenuBar is already registered by appmenu-qt5, skipping Erreur de segmentation valentin@valentin-SATELLITE-L875-10G:~$ gbr3 /usr/bin/gambas3 gb.gui: warning: 'gb.qt4' component not found, using 'gb.qt5' instead appmenu-qt: handleReparent 143 The given QMenuBar is already registered by appmenu-qt5, skipping appmenu-qt: handleReparent 143 The given QMenuBar is already registered by appmenu-qt5, skipping Erreur de segmentation valentin@valentin-SATELLITE-L875-10G:~$ Debugging with Nemiver : valentin@valentin-SATELLITE-L875-10G:~$ which gbr3 /usr/bin/gbr3 valentin@valentin-SATELLITE-L875-10G:~$ which gambas3 /usr/bin/gambas3 valentin@valentin-SATELLITE-L875-10G:~$ nemiver gbr3 /usr/bin/gambas3 valentin@valentin-SATELLITE-L875-10G:~$ I got the attached screenshot.
