(In reply to Andrew Pinski from comment #10)
> GCC 10+ started to reject the code just the same as CLANG does.
Clang doesn't reject it, libc++ does. Clang with libstdc++ accepts it, and so
does GCC trunk (you just need some more headers for recent versions):
#include <string>
#include <streambuf>
#include <istream>
#include <iterator>
#include <algorithm>
void f(std::istream &s, std::string x) {
std::istreambuf_iterator<char> eod;
std::search(std::istreambuf_iterator<char>(s),
eod,
x.begin(),
x.end());
}
Reopened.
