Hi there, I was wondering if it's sensible to add a compile-time check for out
of bounds definitions for arrays like g++ already does for strings.


impulze at localhost ~ $ printf 'int main(){char f[1]="f";}' | g++ -x c++ -
<stdin>: In function ‘int main()’:
<stdin>:1:22: error: initializer-string for array of chars is too long

impulze at localhost ~ $ printf 'int main(){char f[1]="f";}' | clang++ -x c++ -

impulze at localhost ~ $ clang ++ --version
clang version 3.0 (/var/cache/paludis/distfiles/scm/clang
f65076ebf5e8bc5ae7b77fe3c3a65dc5db8d763f)
Target: x86_64-pc-linux-gnu
Thread model: posix

Not sure if this is maybe related tohttp://llvm.org/bugs/show_bug.cgi?id=5028
