Can you provide a (minimal) test case s.t. we can easily reproduce and double-check the problem.
Cmdline/input etc (MASKED, whatever is needed to see it crashing).
Thx

Initializing hashcat v0.46 by atom with 4 threads and 128mb segment-size...
Added hashes from file ..\hashes\A0.M1100.hash: 10 (6 salts)
Added rules from file C:\Utilities\hc\hashcat\KL_rules\KoreLogicRulesAppend4Num.rule: 20000
I "*think*" I have identified the problem (yes it was a problem, but dunno if no more crashes occur when you test). The trac ticket is here:
https://hashcat.net/trac/ticket/186
Please test (when hashcat 0.47 was released) and report if this was indeed fixed.
Thx for reporting!
