Just skip an in irbuild test if running on a free-threaded build, since the IR looks different if free threading is enabled.

Only this one test was failing for me on Python 3.14.0rc1.

Btw, as an option, you can add an opposite marker _withnogil, and have two copies of the problematic test with both markers and the different outputs for each marker (I remember we had something similar for daemon, where the order of error messages depends on whether we use cache or not).

Yeah, that's a good idea. In this case the free threading variant doesn't seem super useful, and a better way to test for the free threading behavior would be to have multi-threaded perf scaling benchmarks. But in the future it seems likely that we'll want separate no-GIL irbuild test cases, and we can implement your idea then.
