            Bug ID: 26891
           Summary: C: Feature-request: diagnostic for assignments of
                    read-only locations (eg string literals)
           Product: clang
           Version: 3.8
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: Frontend
          Assignee: unassignedclangbugs at nondot.org

    Classification: Unclassified

This is a feature-request for Clang to emit a diagnostic related to assignment
to string-only location, as is seen in the test-case. 
The fact that this is UB via const-violation is obvious, but gcc emits a
diagnostic since 4.8 or earlier.

Test case:

int main() {
"abc"[1] = '1';
}
