Bug ID: 104534
Summary: write-strings does not follow C++ standard
Product: gcc
Version: 10.2.1
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: johnsen.david at siemens dot com
Target Milestone: ---
The bug is present in all versions of GCC from 6 to 11 and on GCC trunk.
example file ws.cpp:
#include <iostream>
void f(char*) { std::cout << "This compiler is broken" << std::endl; }
void f(bool) { std::cout << "This compiler is correct" << std::endl; }
int main() {
f("This is supposed to work");
return 0;
}
This program is a valid C++ and the standard is very clear on what the result
should be.
As far as I know, there is no way to make GCC generate this result.
compiled with: c++ ws.cpp
Depending on the command line options, the program can:
* compile (and run incorrectly, -Wnowrite-strings),
* compile with a warning (still run incorrectly, -Wwrite-strings),
* or not compile at all (-Werror -Wwrite-strings).
The only outcome that I can't get is the correct one:
* The program compiles without errors and runs correctly.
Other compilers, such as clang++ and Visual Studio C++, follow the standard.
