Description:
------------
Hi,

there seems to be a regression from PHP 7.3.x to 7.4.x. (Those nasty ZTS bugs that were fixed in PHP 7.2 seem to be back :))

Please use my simple ZTS application:
https://gist.github.com/paresy/3cbd4c6a469511ac7479aa0e7c42fea7

Compile:
g++ php.cpp -Imain -ITSRM -IZend -I. --std=c++11 -Llibs -lphp7 -lresolv -ldl -pthread

I used a minimal PHP build: ./configure '--disable-fpm' '--disable-cgi' '--disable-cli' '--enable-embed=static' '--enable-maintainer-zts' '--disable-all'



Test script:
---------------
<?php

//Leave it empty.

Expected result:
----------------
FINISHED (multiple times)

Actual result:
--------------
��������������������������������zend_mm_heap corrupted

You are missing initialization of file_handle.buf. Does the problem persist if you fix that?

You can also use zend_stream_init_filename() to handle the initialization more reliably.

After fixing that it works ... but there's still this valgrind warning during shutdown:

Possibly it's trying to destroy the realpath cache of the wrong thread?

Sorry for bothering you. This fixes the issue. I also updated my gist.
 [2019-11-07 12:22 UTC] maroszek at gmx dot net 
Yes, those real path leaks remain. I have a separate issue open here: https://bugs.php.net/bug.php?id=78698

I would be glad if you could have a look at it.
