Bug description: imap_header crashing on large data
Description:
------------
imap_header crashes, I've searched the bugs db and found that many people
came across this problem but it hasn't been fixed properly nor has anyone
given too much data to solve it.
php version is 5.2.2 and according to the bugs it seems that upgarding
wouldn't do any good (plus, i'm on a shared host and can't upgrade on my
own).
Reproduce code:
---------------
a message with large header data (229 To addresses) and all kinds of junk
headers, the message is a chain message thats been throught tons of mail
servers & thus have many headers.
Actual result:
--------------
here's the gdb output :
Program received signal SIGSEGV, Segmentation fault.
