Does TEST(WriterTest, WriteUIntPtr) use internal::count_digits<4>?

[denchat]

When I tried to build test in DLL mode, it failed at format-test.exe linking :

LINK: command "C:\PROGRA~2\MIB055~1\2019\BUILDT~1\VC\Tools\MSVC\1420~1.275\bin\Hostx64\x64\link.exe /nologo test\CMakeFiles\format-test.dir\format-test.cc.obj /out:bin\format-test.exe /implib:test\format-test.lib /pdb:bin\format-test.pdb /version:0.0 /machine:x64 /INCREMENTAL:NO /subsystem:console test\test-main.lib test\gmock.lib fmt.lib kernel32.lib user32.lib gdi32.lib winspool.lib shell32.lib ole32.lib oleaut32.lib uuid.lib comdlg32.lib advapi32.lib /MANIFEST /MANIFESTFILE:bin\format-test.exe.manifest" failed (exit code 1120) with the following output:

It's like TEST(WriterTest, WriteUIntPtr) uses internal::count_digits<4>(uintptr_t) which is supposed to stay in implementation test (format-impl-test) only.

However when I look at it :

TEST(WriterTest, WriteUIntPtr) {
  memory_buffer buf;
  fmt::writer writer(buf);
  writer.write_pointer(fmt::internal::bit_cast<fmt::internal::uintptr_t>(
                           reinterpret_cast<void*>(0xface)),
                       FMT_NULL);
  EXPECT_EQ("0xface", to_string(buf));
}

How come it end up refer to internal::count_digits<4>(uintptr_t)?

Should TEST(WriterTest, WriteUIntPtr) be moved to implementation test?

Good catch, thanks! The WriteUIntPtr test does belong to format-impl-test. Fixed in ea2976e.
