The issue came up in #4377.

As a quick workaround we are using the x86 toolchain, but for potentially better build times we should use the amd64_x86 one.

Is this even an issue worth tracking in our tracker? To me this seems like an issue with the MSVC amd64_x86 toolchain. Thus we should probably report a bug to them instead 🤔

I believe it's an issue in the toolchain too, however I think we should leave this open until it's effectively fixed.

We can close it once we switch to amd64_x86 for our x86 build.

The issue actually was unrelated to the toolchain. The problem was that a test-case timed out and for some reason Qt thinks it is a good idea to report this as a stack buffer overflow
