/**
 * Regression test for <https://github.com/libgd/libgd/issues/338>
 *
 * We're testing that reading a JPEG image with gdImageCreateFromJpeg()
 * raises a GD_WARNING for the fatal libjpeg error, but not a GD_ERROR.
 * We also make sure, that the fatal libjpeg error is actually reported.

 * See also ../png/bug00338.c
