--- Comment #9 from Martin Liska <mliska at suse dot cz> ---
Reduced test-case:

$ cat audiovisualwaveform.ii
void memcpy(void *) { ; }
class qfloat16 {
public:
  qfloat16(float) noexcept;
  short b16;
};
qfloat16::qfloat16(float) noexcept {
  __fp16 f16 =3D __fp16();
  memcpy(&f16);
}
class {
public:
  int size();
} AudioVisualWaveformDrawSample_sample;
void AudioVisualWaveformDrawSample() {
  for (int i; i < AudioVisualWaveformDrawSample_sample.size(); i++)
    qfloat16 min =3D 0;
}

$ readelf -w audiovisualwaveform.o >/dev/null
readelf: Warning: There is an overlap [0x42 - 0x39] in .debug_loc section.
