Let me know if you see the same, or if that doesn't matter.
Edit: one thing I just noticed is that this Macro target was not there in the 5.9 branch of swift-syntax, so maybe the issue is because I'm trying to build this Macro example from latest swift-syntax trunk with that Swift 5.9.0 build?
Second edit: I just tried the same example with the latest Sep. 1 5.9 snapshot build and cannot reproduce the crash, so that 5.9.0 crash must not be because of the Swift version. Maybe some other commit on the release/5.9 branch fixed the issue, though I don't see what it could be, or that 5.9.0 CI build I linked above is just broken for some spurious reason. @rintaro, you may want to run the final 5.9.0 builds through this test to make sure.
This looks exactly like the crash I fixed here, which landed in the 5.9.0 branch after the toolchain you mention was built. That fix has been on main and release/5.9 for a while longer, we just pulled it into release/5.9.0 fairly late.
great job to everyone who worked on this! i have been wanting to try out the macros feature for a while now and iām glad this made it into the 5.9 release.
Thanks for the explanation. I just wanted to make sure whatever fix made it work for the 5.9 branch was also pulled into the separate 5.9.0 branch, sounds like it has.
