@ahoppen oh.. I try finded issue for apple developer forums, but I don't finded issue content... so.. Could you please give me the URL for that content?

The comment was automated that this GitHub issue was synced to Apple’s internal issue tracker. There was no action necessary from you.

The issue appears to be in docc because docc shouldn’t cause a crash, independent of swift-syntax. I’m moving the issue to that repo.

This error happens before DocC is ever invoked. It looks like it's the clang -extract-api command that fails with an error.
