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: unassignedclangb...@nondot.org
Reporter: andrey....@gmail.com
CC: llvm-bugs@lists.llvm.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';
}
