@jkelling Do you have any news related to this bug?

@alpaka-group/alpaka-maintainers I was not able to work around the GCC bug. I disabled for now the requirement to pass the CI tests for: - linux_nvcc-11.1_gcc-10_debug - linux_nvcc-11.2_gcc-10_debug This avoids that...

Unluckily it is not enough to mark the tests as not required (you need still admin rights to merge the PR), therefore the combination nvcc+GCC10.3 is currently disabled. #1302 :-(

I reopened this issue, the issue is still not solved, only handled by a workaround.

> The same error occurs with GCC 11.0.1, libstdc++ 10.3 and CUDA 11.2, which is weird because nvcc causes GCC 11 to not use libstdc++ 11, but version 10. If...

@edrozenberg Thanks for the clarification :+1: and the links to the corresponding gcc bug reports.

We have the header validation test, where we check if all includes are available, I am not sure if we perform this test for each accelerator but if this could...

From the view of an programmer the case 4 would be the best one because sometimes it is useful to mic and atomicAdd and atomicExch. In the current alpaka implementation...
