--- Comment #1 from Eric Gallager <egallager at gcc dot gnu.org> ---
Confirmed that gcc errors and clang doesn't:
$ /usr/local/bin/g++ -c -Wall -Wextra -pedantic -Wshadow 78388.cc
78388.cc: In function ‘void f()’:
78388.cc:4:17: error: declaration of ‘void i’ shadows template parameter
(int((void(i), 1))) + 0;
^
78388.cc:1:10: note: template parameter ‘i’ declared here
template<int i>
^~~
$ /sw/opt/llvm-3.1/bin/clang++ -c -Wall -Wextra -pedantic -Wshadow 78388.cc
78388.cc:4:25: warning: expression result unused [-Wunused-value]
(int((void(i), 1))) + 0;
~~~~~~~~~~~~~~~~~~~ ^ ~
1 warning generated.

Function-style casts are evil, see bug 69818 (which is asking for a warning in
a different context, but still)
