Description Andreas Schwab 2015-11-15 14:43:18 UTC 
When building with --enable-checking=release:

../../gcc/gcc/cp/tree.c: In function ‘tree_node* build_cplus_array_type(tree, tree)’:
../../gcc/gcc/cp/tree.c:894:44: error: suggest parentheses around assignment used as truth value [-Werror=parentheses]
        = TYPE_NEEDS_CONSTRUCTING (elt_type));
                                            ^

../../gcc/gcc/cp/tree.c:896:51: error: suggest parentheses around assignment used as truth value [-Werror=parentheses]
        = TYPE_HAS_NONTRIVIAL_DESTRUCTOR (elt_type));
                                                   ^
Comment 1 Dominique d'Humieres 2015-11-17 14:30:08 UTC 
I also see that on x86_64-apple-darwin14. Note that the "suggest parentheses ..." is quite unhelpful.
