 [2016-09-11 17:01 UTC] pl dot lamballais at flashover dot fr 
Description:
------------
Segmentation fault (11) when using an empty input file html object.



Test script:
---------------
echo "<input type=\"hidden\" value=\"myForm\" name=\"";  
echo ini_get("session.upload_progress.name");
echo "\">\n";
echo "<input type=\"file\" name=\"tnews_img\" id=\"liste_upload\">\n";

When you select a file and upload, it works. But if you don't select file and submit, you get  a "Segmentation fault (11)"  in Apache.

Was OK on PHP5.
The problem came from the hidden file. With only the input type file, it works.

This is likely a duplicate of bug #72724, which has been fixed in PHP 7.0.11.

Does that still happen with any of the supported PHP versions[1]?
