           Summary: clang-format does not handle lambda init capture by
                    reference

            Status: NEW
          Severity: normal

Example of `clang-format -style=google` failing for lambda init capture
by-reference

When a lambda capture list includes an init capture by reference, clang-format
will not change any of the lambda code.

I attached an example C++ file which includes a lambda with a capture list that
exceeds the line limit in the body and the capture list.  When running
`clang-format -style=google example.cpp`, neither line is wrapped to the 80
character limit.  If capture list only uses by-value init capture (i.e. remove
the '&'s), the file will be formatted correctly.
