Description:
------------
Segmentation Fault if we try getimagesize on zip:// strem

All was ok on php 7.0.16, this is related to phpoffice/phpexcel library

example - just try any file to open, we tried to get image from excel
file so putting here example for it
getimagesize('zip:///home/user/workbook.xlsx#xl/media/image1.gif');

If we trying to open this file via fopen
$h = fopen('zip:///home/user/workbook.xlsx#xl/media/image1.gif', 'br');

PHP Warning:  fopen(zip:///home/user/workbook.xlsx#xl/media/image1.gif):
failed to open stream: operation failed in ...

Same time file_get_contents working well
