Comment (by Ryan.Livingston@…):

 Just encountered this in our code base. We ran clang-tidy with modernize-
 use-nullptr which converted some code from:

 {{{
 if (aBoostFunction == NULL) {
     ...
 } else {
     aBoostFunction(...);
 }
 }}}

 to:

 {{{
 if (aBoostFunction == nullptr) {
     ...
 } else {
     aBoostFunction(...);
 }
 }}}

 This change caused the comparison to return false as shown above and the
 empty function was invoked.
