title: Is gdalwarp broken? reprojection failed
body: <p>I use gdalwarp to get a planisphere with the EPSG 4326 projection (equidistant cylindrical projection). Before with GDAL 2 I had no problem to use gdalwarp with this command :</p>
  <p><code>gdalwarp -te lonMin latMin lonMax latMax -t_srs EPSG:4326 sphere.tiff planisphere.tiff</code></p>
  <p>Example</p>
  <p><code>gdalwarp -te -100 -10 -60 10 -t_srs EPSG:4326 sphere.tiff planisphere.tiff</code></p>
  <p>But now with GDAL 3.0.4 it returns an error like if I made a mistake in coordinates.</p>
  <p><code>Creating output file that is 0P x 0L. ERROR 1: Attempt to create 0x0 dataset is illegal,sizes must be larger than zero.</code></p>
  <p>Do we need to install something else now? (maybe because now GDAL seems to use PROJ6).</p>
  <p>If someone have the solution or an idea, I will be glad to hear it. Thanks !</p>
