Description

This is with beignet's latest git commit, commit 228775e8, on a Fedora 22 system, but with a vanilla kernel: $ uname -a Linux f22b.localdomain 4.2.0-0.rc4.git4.1.vanilla.mainline.knurd.1.fc22.x86_64 #1 SMP Sat Aug 1 06:31:40 UTC 2015 x86_64 x86_64 x86_64 GNU/Linux

CPU is Intel(R) Core(TM) i5-4570 CPU @ 3.20GHz

When I build the latest John the Ripper version https://github.com/magnumripper/JohnTheRipper/commit/8ebe17a69745dd3f6735c7d1f65884a40c98162e or any other recent commit of the bleeding-jumbo branch

(bleeding-jumbo)src $ make -s distclean; ./configure && make -s clean && make -s -j 16

and then test the wpapsk-opencl format, I get

(bleeding-jumbo)src $ ../run/john --test=0 --format=wpapsk-opencl --verbosity=5 initUnicode(UNICODE, ASCII/ASCII) ASCII -> ASCII -> ASCII Failed to release test userptr object!

Last time I added some debug output (a week ago) I got this information:

Benchmarking: wpapsk-opencl, WPA/WPA2 PSK [PBKDF2-SHA1 OpenCL 4x]... ctx->getErrCode() 1, ctx->getIFENDIFFix() 0, OUT_OF_RANGE_IF_ENDIF 4 ctx->getErrCode() 1, ctx->getIFENDIFFix() 0, OUT_OF_RANGE_IF_ENDIF 4 ctx->getErrCode() 4, ctx->getIFENDIFFix() 1, OUT_OF_RANGE_IF_ENDIF 4 ASSERTION FAILED: !(ctx->getErrCode() == OUT_OF_RANGE_IF_ENDIF && ctx->getIFENDIFFix()) at file /home/fd/git/beignet/backend/src/backend/gen_program.cpp, function virtual gbe::Kernel* gbe::GenProgram::compileKernel(const gbe::ir::Unit&, const string&, bool), line 197

Is John the Ripper doing something wrong here, or does beignet need to be fixed?
