Bug ID: 64936
Summary: regex, ECMA treated as posix
Product: gcc
Version: 4.9.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: c++
Assignee: unassigned at gcc dot gnu.org
Reporter: pierreblavy at yahoo dot fr
Hi!
I've tested gcc regex with the following code (seen on
http://en.cppreference.com/w/cpp/regex/syntax_option_type). According to this
website, I expect ECMA to match zzxa, and not zzxayy. I don't know if it's gcc
or cppreference.com that's wrong.
--- test code ---
int main()
{
std::string str = "zzxayyzz";
std::regex re1(".*(a|xayy)"); // ECMA
std::regex re2(".*(a|xayy)", std::regex::extended); // POSIX
std::cout << "Searching for .*(a|xayy) in zzxayyzz:\n";
std::smatch m;
std::regex_search(str, m, re1);
std::cout << " ECMA (depth first search) match: " << m[0] << '\n'; //expect
zzxa, have zzxayy ==> WRONG
std::regex_search(str, m, re2);
std::cout << " POSIX (leftmost longest) match: " << m[0] << '\n'; //expect
zzxayy, have zzxayy ==> OK
}

Please read https://gcc.gnu.org/bugs/ -- your testcase is incomplete and you
didn't provide the requested information. Did you search for existing bugs and
determine this is not a duplicate of PR61424?
