/**

 * 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
