The name __lambda, like all names beginning with "__", is reserved to the
implementation.

In addition, some identifiers are reserved for use by C++ implementations and
standard libraries (17.6.4.3.2) and shall not be used otherwise; no diagnostic
is required.

— Each name that contains a double underscore _ _ or begins with an underscore
followed by an uppercase letter (2.12) is reserved to the implementation for
any use.

I'll fix 4.8 to avoid crashing on this testcase, but I don't want to change the
release branches.
