When block-capturing a variable with a non-trivial destructor,

make sure to mark the destructor.  This normally isn't required,
because the destructor should have been marked as part of the
declaration of the local, but it's necessary when the variable
is a parameter because it's the call sites that are responsible
for those destructors.
