--- Comment #1 from Reid Kleckner <rnk at google.com> ---
The error comes from instruction selection for Windows EH instructions:
fatal error: error in backend: Cannot select: 0x55b833e46688: ch = catchret

Basically, nobody has implemented exception handling for Windows ARM 32. You
can work around the issue by disabling EH with -fno-exceptions.
