Image of version and processes
Disabling LLVM allows the project to be build (as expected).
Additional information from the customer:
When we were using Xamarin.IOS 22.214.171.1248 the llc process gives strange error message:
* Assertion: should not be reached at /Users/builder/data/lanes/1381/ef65ca51/source/xamarin-macios/external/mono/mono/mini/llvm-jit.cpp:753
And the build fails. This happened with our full solution, not the sample.
I have tried the sample on v. 126.96.36.199, it hangs. And on the latest version (188.8.131.52) the sample still hangs.
