SYCL: Runtime-Error when initialising a queue

Question

When initialising a queue in SYCL with ComputeCpp I get a Runtime-Error using Visual Studio 2022. Also I tried exact the same code used on the Codeplay Guide. I'm able to trigger this error just by initialising a queue, without selecting any device or something else. (selecting one doesn't help either)

#include <CL/sycl.hpp>
int main(int, char**) {
    cl::sycl::queue queue;

    return 0;
}

(Unhandled exception at 0x00007FF92F544FD9 in LearningComputeCpp.exe: Microsoft C++ exception: std::bad_array_new_length at memory location 0x0000005986CFF110.)

I installed ComputeCpp using the Windows installer and manually included it, aswell as OpenCL. (I'm using an AMD Radeon HD7900 GPU)

To find out if you have a supported processor with drivers that can be used by ComputeCpp, use the "computecpp_info" command. Instructions can be found here and this will show whether your device is supported.

The AMD drivers don't support SPIR fully though so I expect you will not be able to use this GPU with ComputeCpp.

Alternatively you could use DPC++ or hipSYCL, both of which support AMD GPUs.

According to "computecpp_info" my GPU wasn't tested on my OS. Sadly I couldn't get DPC++ or hipSYCL to run on my system. I gues I'll stick to OpenCL or Compute Shaders. I'm just trying to create a small educational project.
