Here's the link to a script that exhibits this problem 100% of the time on my
PPC/YellowDog server as well as a production machine at phpwebhosting.com:
http://www.jump9.com/_testcrypt.txt
I've tried this under several version of php (including the current 4.0.6) as well as
with every available release of libmcrypt (2.4.7-2.4.15) all without effect. Given
that I have the same problem on a production webserver at phpwebhosting as I do on my
own homemade PPC linux box I'm guessing this is real problem...
Any thoughts would be greatly appreciated...

Here's an example:
If encrypt the string "Reed, Phyllis" with the key "70094cc48e1a23bf6fec60c2db6e4b71"
using blowfish in CBC mode mycrypt will seg fault. However, if I change the string to
"Reed,Phyllis" (no space) everything's fine. Removing a chacter from the end (""Reed,
Phylli") doesn't fix the problem though, so it's apparently not length related.
Very strange indeed...

Hi,
This still seems to be a problem in 4.0.6. I'm pretty sure that it is caused by
specific strings being passed into mycrypt, however, I'm not sure what string
characteristics cause the problem.

Should be fixed in CVS now. Fix will be in PHP 4.0.6.
If this happens with it too, reopen this bug report.

here's the back trace (again without db symbols) of the crash when it happens after my
script has completed execution:
