Optimized kernel giving different results
#1
I was writing some rules and decided I should use a simple set of md5 hashes to test the rules. In doing this I noticed some behavior I did not expect. With the optimized kernel, the result stored in the pot file is missing the rules generated part of the match.

So for example, when running the optimized kernel like so:

./hashcat -m 0 -r rules/T0XlC-insert_00-99_1950-2050_toprules_0_F.rule -O forest2020.hash forest2020.txt

output looks like this:

./hashcat --show forest2020.hash 
605fa385f80a89a3a3d3a6a728fbc3b9:forest
f379cfd7a55b621577a8389d1817a102:forest

If I delete the .pot file and run again omitting the -O flag, I get the correct results:
605fa385f80a89a3a3d3a6a728fbc3b9:forest2020
f379cfd7a55b621577a8389d1817a102:forest

Is this intended behavior? I'm using latest git pull as of today:
