             Bug #: 11702
           Summary: Low-quality diagnostic with block literal + trailing
                    return type
           Product: clang
           Version: unspecified
          Platform: PC
        OS/Version: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: C++0x
        AssignedTo: unassignedclangbugs at nondot.org
        ReportedBy: sharparrow1 at yahoo.com
                CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
    Classification: Unclassified


Testcase:

void (^a)() = ^() -> void {};

Gives the following diagnostic:

error: function with trailing return type must specify return type 'auto', not
'<dependent type>'
1 error generated.

This diagnostic is rather confusing, and doesn't actually point at anything.
