Re: [PHP-DEV] base64_encode() memory issue

[Andi Gutmans]

Do you have a patch which you think should be applied? If not, can you send 
a reproducing script (a short one). Maybe you want to run it through 
valgrind and see where the damage is done.

Hi,
I'm not sure how to test what I noticed, so I figured I would post this here
and see if any of you could test it and see if I'm correct. When I test this
in a non-PHP environment with malloc(), this does present a problem however,
and when running segfaults randomly appear because of it.
In base64.c, the string is closed with a \0 byte, but this one byte is never
allocated. Since it's just 1 byte, this often happens without causing
trouble, but every once in a while it does cause a segfault. I hope someone
can confirm this.
Happy holidays,
Ron
