             Bug #: 12374
           Summary: Warn on usage of -> on array
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: jduba at izotope.com
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified


Version:
Apple clang version 3.1 (tags/Apple/clang-318.0.58) (based on LLVM 3.1svn)
Target: x86_64-apple-darwin11.3.0
Thread model: posix

compiled with -Weverything


The following should generate a warning:

struct s { void f(); }

int main(int argc, char* argv[]) {
 s vals[4];
 vals->f();

 return 0;
}


it is unlikely that a user wants to access the first element of an array by
using vals->f(); rather than vals[0].f();
