Description:
------------
PHP crashed in zend_new_interned_string_int while include PHAR file larger than 2Gb.

static const char *zend_new_interned_string_int(const char *arKey, int nKeyLength, int free_src TSRMLS_DC){

        ...
        ...

        p = (Bucket *) CG(interned_strings_top);
	CG(interned_strings_top) += ZEND_MM_ALIGNED_SIZE(sizeof(Bucket) + nKeyLength);

#if ZEND_DEBUG_INTERNED_STRINGS
	mprotect(CG(interned_strings_start), CG(interned_strings_end) - CG(interned_strings_start), PROT_READ | PROT_WRITE);
#endif
	
	p->arKey = (char*)(p+1);
	memcpy((char*)p->arKey, arKey, nKeyLength);  <- crash here
	if (free_src) {
		efree((void *)arKey);
	}

Test script:
---------------
Python script to create PHAR file (please run with Python 3):
#! /usr/bin/env python3

import zipfile

fname = 'test.txt'

with zipfile.ZipFile('zip1.zip', 'w') as z:
    z.writestr(fname, 'a'*0x80001000)
    

PHP script:
<?php
    ini_set('memory_limit', -1);
    
    include __DIR__ . '/zip1.zip';
?>

Expected result:
----------------
No crash

Actual result:
--------------

Doesn't look like security issue - you're including a zip file, that's not what is commonly done.

I tested to include a PHP with length larger than 2Gb and this still happen. I think we have problem when include any file larger than 2Gb. This could cause PHP to crash and denial of service.

Please provide a reproducing case where it's not doing something no real PHP programmer would do, like including 2GB zip file as PHP.

Yes, I agree with you. No PHP developer could include file larger than 2Gb. But please change it to Bug and fix it.

To be clear: this is not Phar related; not even related to ZIP
archives, but rather that you're trying to include some binary
data (likely the same would happen if the same data where passed
as script to php).

Anyhow, I cannot reproduce the crash with PHP-7.4, so I'm assuming
this issue has been resolved.  Or can somebody else still
reproduce it with any of the actively supported PHP versions[1]?
