+Subject: [PATCH] Fix #66387: Stack overflow with imagefilltoborder
+
+The stack overflow is caused by the recursive algorithm in combination with a
+very large negative coordinate passed to gdImageFillToBorder(). As there is
+already a clipping for large positive coordinates to the width and height of
+the image, it seems to be consequent to clip to zero also.
