I've installed https://software.intel.com/en-us/articles/opencl-drivers#latest_CPU_runtime (OpenCL™ Runtime 16.1.1 for Intel® Core™ and Intel® Xeon® Processors - 64 Bits) and it shows up correctly running `hashcat -I`. I've also tried version 16.1.2 with the same result.\r\n\r\nWhen I try to run any benchmark it stalls with a segfault:\r\n```\r\n./hashcat --opencl-platforms=2 -b\r\nhashcat (v4.1.0-68-g1b30a1d6+) starting in benchmark mode...\r\n\r\nBenchmarking uses hand-optimized kernel code by default.\r\nYou can use it in your cracking session by setting the -O option.\r\nNote: Using optimized kernel code limits the maximum supported password length.\r\nTo disable the optimized kernel code in benchmark mode, use the -w option.\r\n\r\nOpenCL Platform #1: NVIDIA Corporation, skipped or no OpenCL compatible devices found.\r\n\r\nOpenCL Platform #2: Intel(R) Corporation\r\n========================================\r\n* Device #1: Intel(R) Xeon(R) CPU E5-2623 v4 @ 2.60GHz, 8009/32039 MB allocatable, 8MCU\r\n\r\nBenchmark relevant options:\r\n===========================\r\n* --opencl-platforms=2\r\n* --optimized-kernel-enable\r\n\r\nHashmode: 0 - MD5\r\n\r\nSegmentation fault (core dumped)\r\n```\r\n\r\nI've already tryed compiling the latest version from git, also tried to compile with `DEBUG=1` and get a dump with `gdb`:\r\n\r\n```\r\nmake clean\r\nDEBUG=1 make\r\nulimit -c 999999999999\r\n./hashcat -b\r\n(core dumped)\r\ngdb ./hashcat core\r\n```\r\nthere isn't any core-file present, where would I look for that?\r\n\r\nI'm running `4.12.14-lp150.12.4-default #1 SMP` on an openSUSE Leap 15.0 system. Hashcat has no trouble when running it on the graphics-card - the card is rather slow though, so I'd like to see if it works better on the CPU.\r\n```\r\n./hashcat -I\r\nhashcat (v4.1.0-68-g1b30a1d6+) starting...\r\n\r\nOpenCL Info:\r\n\r\nPlatform ID #1\r\n  Vendor  : NVIDIA Corporation\r\n  Name    : NVIDIA CUDA\r\n  Version : OpenCL 1.2 CUDA 9.1.84\r\n\r\n  Device ID #1\r\n    Type           : GPU\r\n    Vendor ID      : 32\r\n    Vendor         : NVIDIA Corporation\r\n    Name           : GeForce GT 710\r\n    Version        : OpenCL 1.2 CUDA\r\n    Processor(s)   : 1\r\n    Clock          : 954\r\n    Memory         : 243/972 MB allocatable\r\n    OpenCL Version : OpenCL C 1.2 \r\n    Driver Version : 390.67\r\n\r\nPlatform ID #2\r\n  Vendor  : Intel(R) Corporation\r\n  Name    : Intel(R) OpenCL\r\n  Version : OpenCL 2.0 LINUX\r\n\r\n  Device ID #2\r\n    Type           : CPU\r\n    Vendor ID      : 8\r\n    Vendor         : Intel(R) Corporation\r\n    Name           : Intel(R) Xeon(R) CPU E5-2623 v4 @ 2.60GHz\r\n    Version        : OpenCL 2.0 (Build 25)\r\n    Processor(s)   : 8\r\n    Clock          : 2600\r\n    Memory         : 8009/32039 MB allocatable\r\n    OpenCL Version : OpenCL C 2.0 \r\n    Driver Version : 1.2.0.25\r\n```\r\n\r\nAny help appreciated!"}}
