C++ template template argument types deduction

I have code that finds and prints out matches of a pattern as going over the container of strings. Printing is performed in the function foo that is templated

The code

#include <iostream>
#include <algorithm>
#include <iterator>
#include <vector>
#include <string>
#include <tuple>
#include <utility>

template<typename Iterator, template<typename> class Container>
void foo(Iterator first, Container<std::pair<Iterator, Iterator>> const &findings)
{
    for (auto const &finding : findings)
    {
        std::cout << "pos = " << std::distance(first, finding.first) << " ";
        std::copy(finding.first, finding.second, std::ostream_iterator<char>(std::cout));
        std::cout << '\n';
    }
}

int main()
{
    std::vector<std::string> strs = { "hello, world", "world my world", "world, it is me" };
    std::string const pattern = "world";
    for (auto const &str : strs)
    {
        std::vector<std::pair<std::string::const_iterator, std::string::const_iterator>> findings;
        for (std::string::const_iterator match_start = str.cbegin(), match_end;
             match_start != str.cend();
             match_start = match_end)
        {
            match_start = std::search(match_start, str.cend(), pattern.cbegin(), pattern.cend());
            if (match_start != match_end)
                findings.push_back({match_start, match_start + pattern.size()});
        }
        foo(str.cbegin(), findings);
    }

    return 0;
}

When compiling I've got an error that types deduction has failed due to inconsistency of iterators being provided, their types turn out to be diverse.

GCC compilation error:

prog.cpp:35:9: error: no matching function for call to 'foo'
        foo(str.cbegin(), findings);
        ^~~
prog.cpp:10:6: note: candidate template ignored: substitution failure [with Iterator = __gnu_cxx::__normal_iterator<const char *, std::__cxx11::basic_string<char> >]: template template argument has different template parameters than its corresponding template template parameter
void foo(Iterator first, Container<std::pair<Iterator, Iterator>> const &findings)
     ^
1 error generated.

Clang's output:

main.cpp:34:9: error: no matching function for call to 'foo'
        foo(str.cbegin(), findings);
        ^~~
main.cpp:9:6: note: candidate template ignored: substitution failure [with Iterator = std::__1::__wrap_iter<const char *>]: template template argument has different template parameters than its corresponding template template parameter
void foo(Iterator first, Container<std::pair<Iterator, Iterator>> const &findings)

What am I not catching? Is my utilization of template template types deduction wrong and appears an abuse from the standard's point of view? Neither g++-9.2 with listdc++11 nor clang++ with libc++ are able to compile this

Thank you
