--- Comment #1 from Richard Smith <richard-llvm at metafoo.co.uk> ---
Thanks for the report.

The behaviour in clang 8 and before is a bug. SourceRanges throughout clang are
represented as the start locations of the first and last tokens in the range.
This is a common source of surprise for users of SourceRange, but it is the
documented behaviour and is a design choice, not a bug.

We do not provide any API stability guarantees for our C++ API. If you want a
stable API that we are careful to ensure does not change between versions, our
libclang C API is designed for that purpose.

This is unfortunate, but I think there's not really anything we can do to help
you.
