Invalid address specified to RtlFreeHeap

[decastyle]

Windows 10 LTSC Build 19044

I use cmake version 3.31.4, gcc 14.2.0, Vulkan SDK 1.4.304.0, Qt 6.8.1

After I initialize filename, memory gets corrupt at the end of VulkanRenderer::initResources()

What exactly goes wrong here and how to fix it?

Thanks in advance.

=========== vulkanrenderer.cpp ===========

void VulkanRenderer::initResources()
{
    VkDevice dev = m_window->device();
    m_devFuncs = m_window->vulkanInstance()->deviceFunctions(dev);

    QString filename = "aaa"; // Issue is there

    printf("End of void VulkanRenderer::initResources()\n");
}

=========== vulkanrenderer.h ===========

#ifndef VULKANRENDERER_H

    void startNextFrame() override;

protected:
    QVulkanWindow *m_window;
    QVulkanDeviceFunctions *m_devFuncs;
    float m_hue = 0;
    
};

#endif // VULKANRENDERER_H

First observation is that initializing filename there seem to have no purpose i.e., create it and immediately destroy it. Should not cause an issue though.

You look to be using the Qt Online Installer deployment of Qt 6.8.1 for MingW. IIRC, this is built with GCC 13.x (certainly what shipped with the online installer for me). You claim to be building your application with GCC 14.x. Possible that you have a ABI difference from mixed libraries.

Thank you a lot! Using GCC 13.x solved the problem. It also solved the issue with WIN32_EXECUTABLE TRUE CMake target property causing the window to crash early.

For anyone else encountering this issue, set the environment variable for the compiler path to point to Qt/Tools/.../bin directory to make sure that GCC 13.x is used instead of GCC 14.x
