Compiler error on Android only

The following code snippets compile ok on macOS and iOS but fails on Android


    const int nMaxNFFT = 2048;
    univector<complex<fbase>, nMaxNFFT> spectrum = scalar(qnan);
    const int nFramesWinOv = AUDIO_BUFFER_SIZE;
    univector<fbase, nFramesWinOv> reals = make_univector(pAudio, nFramesWinOv);
    reals *= my_win;
    univector<complex<fbase>, nFramesWinOv> inVec(make_complex(reals, zeros()));
    my_dft.execute(spectrum, inVec, m_workBuf);

    univector<complex<fbase>, nMaxNFFT/2> specHalf = scalar(qnan);
    std::copy(spectrum.begin(), spectrum.begin()+nFFT/2, specHalf.begin());

    univector<fbase, nMaxNFFT/2> amps = cabs(specHalf/m_nFFT);
    univector<fbase, nMaxNFFT/2> dbs = amp_to_dB(amps);
    auto clamped = clamp(dbs, -200.f, 0.f);  // failed to compile here
