@burgholzer, we suddenly get segmentation faults in the C++ and Python tests. The tests failed right from the start, before the upgrade to C++20. The failing tests are all testing the hybrid circuit simulator in DD mode. Do you have any idea which change in Core could cause this? 🤔

That is certainly strange. The Windows tests in Debug mode are most helpful in this case: https://github.com/munich-quantum-toolkit/ddsim/actions/runs/16657462556/job/47146024096#step:6:1
I'll the check the mqt-core changes. Probably something related to reference counting, but I am not sure. I thought these changes were already in 3.1

[burgholzer]

Hm I don't see any particular change in 3.2 that could have caused this.
I would have suspected munich-quantum-toolkit/core#1020, but that was already part of 3.1

Maybe something on the C++20 went wrong but unnoticed in mqt-core.

At least it's a consistent failure. If you happen to have a Windows (virtual) machine around, running in debug mode with MSVC and a debugger attached is probably the easiest way to identify, what exactly is going wrong.

[denialhaag]

The problem is fixed by munich-quantum-toolkit/core#1088. Once this is merged, I'll create a patch release in Core so that we can revert 1887ab8 and require v3.2.1 here.
