6.1.1 vs 4.5.1 some modes don't work anymore

[oayz]

Hashcat 6.1.1 -a0 works fine, -a5,6,7 - do not, hanging on "Initializing backend runtime for device #1...", memory usage going to max (I have 10GB) then swap files gets beating. Hashcat 4.5.1 works just fine on all modes.

Running on Win7_64, hash / dict don't matter, command line:

hashcat.exe Home.hccapx -t 32 -a 7 -m2500  --self-test-disable ?a?a?a?a example.dict

Anyone seeing something like this? Should be reported long ago - pretty gross so may be something on my side
