SUMMARY | 问题概要
程序退出时偶现段错误。
查看堆栈,程序无法查找到 DTK 单例, DQuickControlColorSelector::onPaletteDestroyed() 函数被固定触发,通过在此函数中添加 dumpObjectTree 等调试信息,触发者来自 ToolTip 。
和ToolTip触发后退出 Palette 等资源的释放可能相关,通过Demo,可稳定复现此问题。
DTK and OS VERSIONS | DTK&系统版本信息
Distribution: v23 0719
Pacakge: dtk6declarative 6.0.16+u003
本地打包编译 6.0.18 基于 c2d07b2abcda620556da392cddb8ef7754c85b5c 测试同样现象
Minimal Reproducible Case Code | 最小复现案例代码
使用QtCreator模板创建 Dtk6 QtQuickApplication,在 Button 中添加 ToolTip 触发代码
代码:
clicktiptest.zip
OBSERVED RESULT | 观察到的结果
多次点击/hover按钮,触发ToolTip显示,程序退出出现段错误(大概40%~60%概率)。

EXPECTED RESULT | 期望的结果
程序正常退出,ToolTip等控件的显示与否不会影响资源释放
