FreeLocaleResult freelocale(locale_type locale) FMT_LOCALE_THROW {

error: /home/sean/projects/fmt/test/posix-mock-test.cc:507:18
cannot overload void freelocale(__locale_struct*) noexcept on noexcept-specifier
  previous declaration at /usr/include/locale.h:180:13
FreeLocaleResult freelocale(locale_type locale) FMT_LOCALE_THROW { 
                 ^

In /usr/include/locale.h it's defined as:

extern void freelocale (locale_t __dataset) __THROW;

I don't know how to make this right on Circle given the current __THROW definition:

#  if defined(__THROW) && \
      ((FMT_GCC_VERSION > 0 && FMT_GCC_VERSION <= 408) || defined(__e2k__))
#    define FMT_LOCALE_THROW __THROW
#  else
#    define FMT_LOCALE_THROW
#  endif

It is some old experimental code that we no longer need, removed in afbcf1e.
