I've found this issue when trying to get static analysis report for Chrome Remote Desktop iOS client.

I run this:
  ninja -C out/ios-analyze -j20 ios_remoting_google_app

and got error like this:

Looks like //build/toolchain/mac/BUILD.gn has not been updated while //build/toolchain/clang_static_analyzer_wrapper.py has been changed quite a bit. The build script also asserts that GOMA is not supported but looks like the bug has already been resolved.

The fix seems to be trivial so I'll work on it.
