Hi,
This bug still exists in the 5.5 branch of PHP (also in 5.5.11), but only in 64 bits. However, it
seems to be resolved in 5.6 beta1 (32 + 64 work).
For your second question, it may be reproduced in > 10% of the files i have tested (more than
4000 tested files).
If you are interested I can send you some of these files by email.
Sincerely,

@jamal, could you please check whether 5.6.0beta1 or the latest 5.5 release is vulnerable for you?
Is that some special ppt file or any?
Thanks.

Thanks for posting the memory dump, but I'd really like to see the backtrace first. I'd
also appreciate you to share the exact ppt file causing this crash.
Thanks
