Question

我的QT应用程序有一个名为“CinemasVisualizerPlugin”的插件，在执行“setStyleSheet（styl）;”行时它崩溃了

但其他linux机器上的代码相同。我怀疑是一些路径问题。

任何输入都会非常有用。感谢

我怀疑是路径问题。

最有可能的是它不是。错误消息报告内存损坏

double free或corruption（out）：0x000000000152dbe0

并且回溯指向您的自定义代码。

Velkans提示是正确的，您应该在调试器（gdb）中运行代码并查看回溯以查找崩溃的原因。如果您无法找到任何内容，则需要更多高级工具，例如valgrind。

如果你不知道如何做到这一点，那么学习它 - 对于每个认真的软件开发人员来说，它都是一项强制性的技能，而你却不会有太大的帮助。通常你的IDE支持这个并且使用起来相当舒服;如果没有时间选择那个。
