--- Comment #2 from Eric Gallager <egallager at gcc dot gnu.org> ---
I made a fuller testcase:
$ cat 55254.cc
#include <string>
int foo(int eighty)
{
std::string foo = std::string(80, '=');
std::string bar = std::string('=', 80);
std::string baz = std::string(int('='), eighty);
(void)foo;
(void)bar;
(void)baz;
if (eighty == 0) {
eighty = '=';
return eighty;
}
return 80;
}
$ /usr/local/bin/g++ -c -Wall -Wextra -Wnarrowing -Wsign-conversion
-Wconversion -pedantic -Weffc++ 55254.cc
55254.cc: In function ‘int foo(int)’:
55254.cc:7:48: warning: conversion from ‘int’ to ‘char’ may change value
[-Wconversion]
std::string baz = std::string(int('='), eighty);
^
$
So, I get a warning, but not where the reporter was requesting it (which is
probably my fault). Confirmed that there could still be a warning for bar.
