This is possibly a side effect of the fix for Bug #43073.

This bug still exists in RC4 and it's critical for me, because with the wrong
value it's no more possible to create valid images (because this is used for
the basline value in ImageFTText()).
Try this to see it:
<?php
$font_file = './arial.ttf';
$text = "Text with\nline-break";
// get minimum size
$box = ImageFTBBox(13, 0, $font_file, $text);
$left = 0;
$top = abs($box[7]);
$width = abs($box[2]) + abs($box[6]);
$height = abs($box[3]) + abs($box[7]);
// add 1px border
$left++;
$top++;
$width+=2;
$height+=2;
// create image and add text
$img = ImageCreateTruecolor($width, $height);
$color = imagecolorallocate($img, 233, 14, 91);
ImageFTText($img, 13, 0, $left, $top, $color, $font_file, $text);
// output
header("Content-Type: image/png");
ImagePng($img);
?>
