@kouvel Can you PTAL? |

The issue is present in 1.0 and 1.1 and given that we have not seen any instances (besides the test) running into this, moving this out to 2.1.0. |

Caught my attention because this is disabled outside issues.targets. This is apparently blocked on #5907 which is a crossgen bug. I tried to /p:PublishReadyToRun=true this test locally and it seems to work fine with crossgen2.

Test case
tests/src/Loader/classloader/generics/regressions/DD117522/Test.csprojcontains a malformed infinitely recursive generic type definition. During app execution, this is correctly handled by throwing aTypeLoadException. However, CrossGen isn't able to handle this correctly, and either crashes with a stack overflow (on Windows) or hangs (on Ubuntu). This test case is being temporarily disabled by dotnet/coreclr#5122, but we need to find a proper fix for this in CrossGen.The text was updated successfully, but these errors were encountered:
