Subject: Get around a GCC 6 warning.
X-Git-Tag: v8.4.2-rc1~2^2
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d4f38d8ec575683f4db10c2814f49da0a43d82e1;p=dealii.git

Get around a GCC 6 warning.

GCC 6.1 now warns (-Waddress) that (since the dynamic cast of an object
back to its own type always succeeds) the address of an object is always
nonzero, so these casts result in tautologies for valid vector types.
