MacMini clBuildProgram():CL_BUILD_PROGRAM_FAILURE, amp_a1.cl, with combination attack

[pmell]

Hello All,

I would be very appreciative of some assistance with this please.

I am getting the following error when attempting a "combination" attack;

Code:

clBuildProgram(): CL_BUILD_PROGRAM_FAILURE Error: out of memory. * Device #2: Kernel hashcat-master/OpenCL/amp_a1.cl build failed - proceeding without this device.

My hardware and base OS are a MacMini (late 2012, 2.3GHz i7, 16GB RAM, Intel HD Graphics 4000 1536 MB) with Mojave;

Code:

$ uname -a Darwin Mac-mini.local 18.6.0 Darwin Kernel Version 18.6.0: Thu Apr 25 23:16:27 PDT 2019; root:xnu-4903.261.4~2/RELEASE_X86_64 x86_64

I have installed the latest version of xcode and compiled hashcat from sources;

Code:

$ ./hashcat -V v5.1.0

I can run hashcat successfully with the following command line options;

Code:

# Dictionary attack. ../hashcat-master/hashcat -O -a 0 -m 500 -o hashes.txt --potfile-path potfile.txt to-crack.txt ../Passwords/rockyou.txt ../hashcat-master/hashcat -O -a 0 -m 500 -o hashes.txt --potfile-path potfile.txt -r ../hashcat-master/rules/best64.rule to-crack.txt ../Passwords/rockyou.txt # brute force attack. ../hashcat-master/hashcat -O -a 3 -m 500 -o hashes.txt --potfile-path potfile.txt to-crack-03.txt -i ?a?a?a?a?a

Each of the above attacks runs fine!

However, when I attempt to run a "Combination" attack (I have generated a wordlist with 500 lines, I had originally tried 3000 lines, but that had the same error), I get the error;

Code:

clBuildProgram(): CL_BUILD_PROGRAM_FAILURE Error: out of memory. * Device #2: Kernel hashcat-master/OpenCL/amp_a1.cl build failed - proceeding without this device.

my command-line and output are;

Code:
