/**
* 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
