imagecreatefromstring() threw the ValueError for a string longer than INT_MAX but did not return, so it went on decoding the data with the exception pending. Return after throwing.

To reproduce:

ini_set('memory_limit', '-1');
try { imagecreatefromstring(str_repeat("x", 2147483648)); } catch (ValueError $e) { echo $e->getMessage(); }

Before: an extra Warning: Data is not in a recognized format. After: only the ValueError.
