Subject: Add parentheses to NM_BIG_BUF macro
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=02e9edd51ff82ebd900a00031b75bc588f9e4d65;p=thirdparty%2Fbind9.git

Add parentheses to NM_BIG_BUF macro

The NM_BIG_BUF macro expands without parentheses, which can cause
incorrect evaluation due to operator precedence when used in
expressions.
