Obviously the above is an extract from production code. We were using lambdas
to wrap individual bits of unsafe code which trips the UB sanitiser. It would
be useful to retain that ability, as having to sprinkle the code with:
struct { auto operator()(auto...) const __attribute__((no_sanitize_undefined))
{ } }()(...);
... seems retrograde.
