Compilation error when both ostream.h and format.h are included

[ukreator]

This simple program does not compile:

#include "fmt/format.h"
#include "fmt/ostream.h"

void func() {
    std::string ss;
    fmt::format(fmt("{}"), ss);
}

First lines of the error:

builds/fmt/include/fmt/format.h:2217:50: error: ambiguous partial specializations of 'formatter<std::__1::basic_string<char>, char, void>'
  formatter<T, typename ParseContext::char_type> f{};

I can confirm this, but if fmt macro is not used then it compiles.

#include "fmt/format.h"
#include "fmt/ostream.h"

void func() {
    std::string ss;
    fmt::format("{}", ss); // ok
    // fmt::format(fmt("{}"), ss); // ERROR!
}

The same error happens if <fmt/printf.h> is included.
