Description
Hello,
We're trying to port Qt6 on FreeBSD.
All modules build, with some adaptations, but we can't launch any application without a segmentation fault.
Here the backtrace of designer Qt6 6.1.2:
* thread #1, name = 'designer', stop reason = signal SIGSEGV: invalid address (fault address: 0x8) frame #0: 0x00000008012749bc libQt6Designer.so.6`QScopedPointer<QObjectData, QScopedPointerDeleter<QObjectData> >::operator->(this=0x0000000000000008) const at qscopedpointer .h:127:16 124 125 T *operator->() const noexcept 126 { -> 127 return d; 128 } 129 130 bool operator!() const noexcept (lldb) bt * thread #1, name = 'designer', stop reason = signal SIGSEGV: invalid address (fault address: 0x8) * frame #0: 0x00000008012749bc libQt6Designer.so.6`QScopedPointer<QObjectData, QScopedPointerDeleter<QObjectData> >::operator->(this=0x0000000000000008) const at qscopedpointer .h:127:16 frame #1: 0x00000008013213ee libQt6Designer.so.6`QObject::isWidgetType(this=0x0000000000000000) const at qobject.h:141:47 frame #2: 0x0000000801496e48 libQt6Designer.so.6`QDesignerPropertySheetPrivate::layout(this=0x000000080f35d180, layoutPropertySheet=0x00007fffffffda48) const at qdesigner_pro pertysheet.cpp:431:20 frame #3: 0x000000080149c3ab libQt6Designer.so.6`QDesignerPropertySheet::property(this=0x000000080c5bdf40, index=65) const at qdesigner_propertysheet.cpp:1040:20 frame #4: 0x000000080149cbd3 libQt6Designer.so.6`non-virtual thunk to QDesignerPropertySheet::property(int) const at qdesigner_propertysheet.cpp:0 frame #5: 0x00000008015f7eda libQt6Designer.so.6`qdesigner_internal::WidgetDataBase::defaultPropertyValues(this=0x00000008063d92d0, name=0x00007fffffffdcf8) at widgetdatabase .cpp:437:34 frame #6: 0x00000008015f7ffe libQt6Designer.so.6`qdesigner_internal::WidgetDataBase::grabDefaultPropertyValues(this=0x00000008063d92d0) at widgetdatabase.cpp:449:42 frame #7: 0x0000000801323272 libQt6Designer.so.6`qdesigner_internal::QDesignerIntegrationPrivate::initializePlugins(formEditor=0x0000000805f9f980) at abstractintegration.cpp: 565:25 frame #8: 0x0000000801324095 libQt6Designer.so.6`QDesignerIntegration::initializePlugins(formEditor=0x0000000805f9f980) at abstractintegration.cpp:750:5 frame #9: 0x00000008009a11c5 libQt6DesignerComponents.so.6`QDesignerComponents::initializePlugins(core=0x0000000805f9f980) at qdesigner_components.cpp:119:5 frame #10: 0x000000000033067a designer`QDesignerWorkbench::QDesignerWorkbench(this=0x00000008063d6000) at qdesigner_workbench.cpp:177:5 frame #11: 0x000000000030af4a designer`QDesigner::parseCommandLineArguments(this=0x00007fffffffe4b8) at qdesigner.cpp:248:23 frame #12: 0x00000000002fb7a4 designer`main(argc=1, argv=0x00007fffffffe5a0) at main.cpp:45:17 frame #13: 0x0000000000275a90 designer`_start(ap=<unavailable>, cleanup=<unavailable>) at crt1.c:76:7 (lldb)
We have also tested qdbusviewer, assistant, qmlscene andlinguist. All the backtraces are available at https://invent.kde.org/adridg/kde-freebsd/-/issues/3
Where do you think the problem comes from?
I can provide a reproducible environment if needed.
Thanks.
