Bug ID: 28776
Summary: Warn for implicit conversion from char literal to int
Product: clang
Version: unspecified
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: Frontend
Assignee: [email protected]

I sometimes want to construct a string with n copies of a char c. However, I
frequently get the order of elements in the constructor mixed up. Rather than
saying std::string(80, '='), I accidentally call std::string('=', 80). If I go
through the trouble to put something in single quotes, I probably mean to pass
it to something expecting a char, not an integer.
Ultimately, I want to get a warning for this code:
#include <string>
int main() {
std::string const probably_wrong('0', 80);
}
