Buffer mapping failure must be handled at below:-
File: gst-plugins-good-1.12.3/gst/law/alaw-encode.c
Function: gst_alaw_enc_handle_frame

...
  gst_buffer_map (buffer, &inmap, GST_MAP_READ);
  linear_data = (gint16 *) inmap.data;
  linear_size = inmap.size;

  alaw_size = linear_size / 2;

  outbuf = gst_audio_encoder_allocate_output_buffer (audioenc, alaw_size);

  g_assert (outbuf);

  gst_buffer_map (outbuf, &outmap, GST_MAP_WRITE);
  alaw_data = outmap.data;
...

Failure of gst_buffer_map must be handled.
