Description Frank Dittrich 2015-09-22 21:57:45 UTC

This is with beignet's latest git commit, commit f9094e59bbef31585bce9d301a0d319a38a11e13 (branch master) on a Fedora 22 system, but with a vanilla kernel:

$ uname -a
Linux f22b.localdomain 4.2.0-1.vanilla.mainline.knurd.1.fc22.x86_64 #1 SMP Tue Sep 1 06:35:39 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/fede4e119167e6f19af8b5b5e9c5f15b638307a9 

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

and then test the descrypt-opencl format, I get:

Comment 1 rongyang 2015-11-27 04:01:22 UTC

I use latest commit of beignet and John the Ripper, this assert has gone.
But there is another assert, I have send a patch "[PATCH] GBE: fix a assert when structure argument's first field don't used.", can you try it?

Thanks

Comment 2 Frank Dittrich 2015-12-22 23:10:30 UTC

Sorry for the delay.
Now I repeated the test with latest beignet commit (032b606f8c5baa53e52b1f55c4f7c0bafdd6ff37), latest John the Ripper (bleeding-jumbo) commit (8d4470ff9f2357fc10c8e5769dbb164eb5118f40) and Linux kernel 4.4.0-0.rc6.git0.1.vanilla.knurd.1.fc22.x86_64.

I didn't find a git commit with a name matching your patch description.

Nevertheless, this time I ran into a different failed assertion:

Comment 3 Frank Dittrich 2015-12-23 00:02:10 UTC

When I get that ASSERTION FAILED error in backend/src/backend/context.cpp, function void gbe::SimpleAllocator::splitBlock(int32_t, int32_t), line 293, there's also a new dmesg line
