Description:
------------
I used the following script to check memory leaks:
<?php
$mime = mailparse_msg_create();
mailparse_msg_free($mime);

echo 'Freed!!' . PHP_EOL;

-------------------
------- Output-----
[root@localhost tmp]# export USE_ZEND_ALLOC=0
[root@localhost tmp]# /usr/local/php/bin/php -d "extension_dir=/root/tmp/php/php-7.0.16/ext/mailparse/modules/" -d "extension=mailparse.so" free.php
Freed!!
Segmentation fault (core dumped)
int(571776)
int(623776)
int(692160)
int(744160)
int(796160)
int(848160)
int(900160)
int(900160)


Expected result:
----------------
After running my script, it doesn't appear memory leaks and segmentation fault.

Actual result:
--------------
Freed!!
Segmentation fault (core dumped)
int(571776)
int(623776)
int(692160)
int(744160)

I have not been able to reproduce the reported segfaults and
memory leaks with mailparse 3.1.0.  Do these still happen to you
with any of the actively supported PHP versions[1]?
