Warning in test suite results: "WARNING: maximum warning/error limit hit"

Recently this warning was popped up on I believe every single suite result:

https://github.com/DynamoRIO/dynamorio/actions/runs/7648183861/job/20840516372?pr=6583
```
WARNING: maximum warning/error limit hit for debug-internal-64!
Manually verify whether it succeeded.
debug-internal-64: 9 tests passed, **** 1 tests failed: ****
code_api|api.rseq
```

I think it is bogus: there is not a large number of errors. Not sure what caused that check to fire with false positives. Filing this issue to investigate.
