PHP Bug Type:     Reproducible crash
Bug description:  imap_headerinfo Address buffer overflow

Description:
------------
While using the imap_headerinfo() function to obtain information about
emails that I check via IMAP, I noticed that PHP complained about
imap_headerinfo() Address buffer overflow.
A bit of investigation revealed that a spam message containing 500+ CC
email addresses caused this issue.

Reproduce code:
---------------
// Send an email with 500+ CCd users. then use imap_headerinfo() to //
obtain all header information.
// [from doc]
$mBox = imap_open("{host:143/imap/novalidate-cert}INBOX}", $username,
$password); // open as imap
$header = imap_header($mBox, 1); // get first mails header

// imap_headerinfo() will crash with the following error:
// PHP Fatal error:  imap_headerinfo(): Address buffer overflow



Expected result:
----------------
I expect to information about the given message number by reading its
headers and returned in an object format

Actual result:
--------------
PHP Fatal error:  imap_headerinfo(): Address buffer overflow
