Subject: [PATCH] Common: Fix -Wcatch-value warnings (catching exceptions by
value)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
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"
