Common: Fix -Wcatch-value warnings (catching exceptions by value)

This fixes some warnings on GCC 8.1:

warning: catching polymorphic type ‘class std::out_of_range’ by value [-Wcatch-value=]
         catch( std::out_of_range )
                     ^~~~~~~~~~~~

This fix is along the same lines as:

* ff1802d7a "Fix Coverity "Big parameter passed by value" warnings"
