[mangod9]

@trylek is this one of the new tests which was added as part of your cycle detection change?

[trylek]

@mangod9 / @carlossanlop - This is a test issue, Crossgen2 timeout when compiling an artificially huge generic graph to exercise a cutoff parameter I added earlier this year to prevent Crossgen2 from OOMing upon such constructs. I merged in a PR slightly simplifying the test to avoid the timeouts in

#90777

but apparently it missed the 8.0 fork on 8/14. I don't think the test is fundamental for .NET 8 validation, after all it's just one of three tests I created for this purpose and the feature itself is rather obscure as the bug has been hit just by a few customers so far.

Carlos, can you please advise what is the most appropriate course of action here? I guess we can either send out shiproom request for backporting my PR or for excluding this test in issues.targets in the 8.0 branch. In both cases I would assume that the change is "non-product" (infra / test only) so it should hopefully fall under tell mode but I may be mistaken. For this issue, that can be marked as a test issue but that won't make the occasional timeouts in the 8.0 branch go away so it will cause a bit of long-term pain when monitoring the runs.

Thanks

Tomas

In fact it's a little weird - my PR includes removal of the issues.targets exclusion of the test that was merged before by someone, maybe Bruce but I'm not sure, when the bug started manifesting, so it should have been disabled prior to my merge of this PR. I guess in such case we should first figure out why the issues.targets exclusion is missing in the 8.0 branch - could it be a bad conflict merge?

[trylek]

OK, I've found it, Bruce merged in the addition to issues.targets in

#90802

on 8/18 so it also missed the fork. In such case I guess a third option is to port just Bruce's PR.
