            Bug ID: 23140
           Summary: Typo correction of pointer-to-member operand raises
                    "placeholders should have been weeded out by now"
                    assertion
           Product: clang
           Version: unspecified
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++
          Assignee: [email protected]
          Reporter: [email protected]
                CC: [email protected], [email protected]
    Classification: Unclassified

consider:
auto lneed = gned.*[] {};

compile with:
~/llvm/Debug+Asserts/bin/clang -cc1 t.cpp -std=c++11

'gned' has been typo corrected to 'lneed':
UnresolvedLookupExpr 0x7483c00 '<overloaded function type>' lvalue (no ADL) =
'lneed' empty

however, semantic analysis continues resulting in this assertion.

instead, I would expect the source to be treated like:
auto lneed = lneed.*[] {};

and raise a diagnostic like:
variable 'lneed' declared with 'auto' type cannot appear in its own initializer
