Bug with complex rule ?

Hi,

I found a bug which is related (I guess) to my previous thread http://hashcat.net/forum/thread-2228.html
from wich I create a TRAC (https://hashcat.net/trac/ticket/154)

The rule file :
contains :
- Swap @ N *XY Swaps character X with Y
- Duplicate last N Z Duplicates last character N times
- Overwrite @ N oNX Overwrites character at position N with X

hashlist :

commandline :

dic.dic contains only the number "1"

result :

The first one (c4ca4..) is the good md5 for '1'.
The second one is wrong.

That's why I guess this is a problem from a null byte somewhere ? like my previous post.

version : oclHashcat-plus-0.14 / Win 7 64bits

Thanks for helping me to understand the problem, coming from this complex rule.
