For what it's worth, I found two recent tickets documenting failures for that very same test: #16897 and #17269.

Hi devs,

https://gitlab.haskell.org/rae/ghc/-/jobs/173504 tells me that T13615 failed -- but only in DEBUG mode. My patch is nowhere near this code. Is this a new fragile test?

The number of fragile tests seems to be growing quickly. And once a test is labeled fragile, we're essentially no longer tracking the test, if I understand correctly. So that's a bit unfortunate.

Thanks,
Richard
