Comment 3 Omair Majid 2019-02-14 00:12:55 UTC

This was fixed upstream and included in the 2.2.2 release: https://github.com/dotnet/coreclr/pull/21534

It will be part of the upcoming .NET Core 2.2.2 release on RHEL 7.

Comment 4 Omair Majid 2019-02-18 19:48:05 UTC

I have added a regression test for this: https://github.com/redhat-developer/dotnet-regular-tests/pull/46

Radka, Can you please sanity check and merge that test and confirm that this issue was fixed in our 2.2.2 update?

Comment 5 Radka Gustavsson 2019-02-28 13:31:44 UTC

This was resolved in the past release.
