vmaDestroyBuffer() destroy everything but VkDeviceMemory

[ghost]

When I vmaDestroyBuffer(), at object destruction, it doesn't destroy VkDeviceMemory hMemory, resulting in error:

Validation Error: [ VUID-vkDestroyDevice-device-05137 ] Object 0: handle = 0x2e2941000000001f, type = VK_OBJECT_TYPE_DEVICE_MEMORY; | MessageID = 0x4872eaa0 | vkCreateDevice(): OBJ ERROR : For VkDevice 0x156f8145c70[], VkDeviceMemory 0x2e2941000000001f[] has not been destroyed. The Vulkan spec states: All child objects created on device must have been destroyed prior to destroying device (https://vulkan.lunarg.com/doc/view/1.3.268.0/windows/1.3-extensions/vkspec.html#VUID-vkDestroyDevice-device-05137)

after i destroy my device.

Function vmaCreateBuffer creates two objects: VkBuffer and VmaAllocation. When the buffer is no longer needed, you should destroy them both by passing them to vmaDestroyBuffer. Do you pass them both, the buffer and the allocation object?

An allocation represents a piece of device memory.

• If VMA decided or was explicitly asked (using VMA_ALLOCATION_CREATE_DEDICATED_MEMORY_BIT flag) to create a dedicated memory block for the allocation, it would represent a separate VkDeviceMemory object. It will get destroyed when you pass the allocation to vmaDestroyBuffer.
• If VMA decided to assign a piece of a larger memory block for the allocation, that memory block may stay after you destroy the buffer and the allocation object.

You don't need to think about it as long as you respect the correct order of deinitialization, which is:

for each buffer:
    vmaDestroyBuffer(g_Allocator, buffer[i], bufferAllocation[i]);
vmaDestroyAllocator(g_Allocator);
vkDestroyDevice(...);

So, my main question is: Did you call vmaDestroyAllocator?

I have the same question and calling the vmaDestroyAllocator didnt do the trick

I managed to do a very brief MRE, minimal reproducible example.

    vmaDestroyBuffer(m_allocator, m_vertex_buffer.buffer, m_vertex_buffer.allocation);
    vmaDestroyAllocator(m_allocator);

e.g.

Do make sure to destroy the allocator prior to the device according to deinitialization order as mentioned by @adam-sawicki-a ; not doing so is only case where I seem to be able to reproduce that error
