vkCreateDevice still failed with VK_ERROR_INITIALIZATION_FAILED when creating large numbers of logic device .

According to this thread( “Logical device creation maximum limit” ), it seems that this problem has been fixed. But when I run the following program, vkCreateDevice still failed with error code VK_ERROR_INITIALIZATION_FAILED. The maximum number of devices I can create is 42.

#include "vulkan/vulkan.hpp"
#include <cassert>
#include <vector>
#include <iostream>

int main() {

    std::vector<vk::Instance> instances;
    std::vector<vk::Device>   devices;

    try {

        for( ; true; ) {

            vk::InstanceCreateInfo instanceInfo {};
            instances.push_back( vk::createInstance( instanceInfo ) );

            auto physicalDevices = instances.back().enumeratePhysicalDevices();
            if( 0 == physicalDevices.size() )
                return 0;

            vk::DeviceQueueCreateInfo deviceQueueCreateInfo {};
            deviceQueueCreateInfo.queueFamilyIndex = 0;
            deviceQueueCreateInfo.queueCount = 1;

            vk::DeviceCreateInfo deviceCreateInfo {};
            deviceCreateInfo.queueCreateInfoCount = 1;
            deviceCreateInfo.pQueueCreateInfos = &deviceQueueCreateInfo;
            auto device = physicalDevices.front().createDevice( deviceCreateInfo );
            if( !device ) {
                throw 0;
            }
            devices.push_back( device );
        }
    }
    catch( std::system_error e ) {
        std::cout << e.what() << std::endl
            << e.code() << std::endl;
    }
    catch( ... ) {
    }

    for( auto device : devices )
        device.destroy();
    for( auto instance : instances )
        instance.destroy();
    printf( "Maximum device is %d\n", devices.size() );
    return static_cast<int>( devices.size() );
}
