Subject: Change some dereferences to pointer arithmetic.
X-Git-Tag: v9.1.0-rc1~1132^2~1
X-Git-Url: https://gitweb.dealii.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4664128c23589a16cd64588b19a9d5cf19a6063d;p=dealii.git

Change some dereferences to pointer arithmetic.

This avoids dereferencing (and then calculating the address of) an entry
one past the end.
