--- Comment #2 from Eric Gallager <egallager at gcc dot gnu.org> ---
g++ now prints a warning from -Wint-in-bool-context for it:
$ /usr/local/bin/g++ -c -Wall -Wextra -pedantic 63519.cc
63519.cc: In function ‘int foo(bool, int, int, int)’:
63519.cc:3:11: warning: ‘*’ in boolean context, suggest ‘&&’ instead
[-Wint-in-bool-context]
return x * a ? y : z;
~~^~~
$
Confirming that a warning from -Wparentheses is still missing though. Also the
-Wint-in-bool-context one could do better and add a fix-it hint, seeing as it
already has a suggestion in the message.
