Error while running hashcat: llvm_codegen: Assertion error == 0 failed...

[qgrosperrin]

Hi all, 

I'm having the following error when trying to use hashcat (up-to-date from apt-get repos). Here with --stdout flag in combination with a mask modifier.

Code:

# hashcat -m 0 -a 3 -1 'hasct' --stdout ?1?1?1 
hashcat: common.c:108: llvm_codegen: Assertion `error == 0' failed.
Aborted

I'm using the following OS (I know it doesn't handle OpenCL well but it worked up until now so hopefully my problem can be solved ^^)

Code:

# uname -a
Linux redonion 4.0.0-kali1-amd64 #1 SMP Debian 4.0.4-1+kali2 (2015-06-03) x86_64 GNU/Linux

It seems I get the same problem when trying to actually crack some hashes (with or without the -r flag):

Code:

hashcat -a 0 -m 300 hashes-hc /usr/share/wordlists/rockyou.txt -r ./resources/tools/password_cracking/Hob0Rules/hob064.rule --force

Anyone has any idea what is going on and how to solve it ?
Thanks

Probably just (yet another) The-Distribution-Which-Does-Not-Handle-OpenCL-Well (Kali) issue. Can you try on a different OS?

[DanielG]

Several google results regarding the error llvm_codegen: Assertion 'error == 0' failed indicate that installing 'clang' resolved this.

sudo apt-get install clang-3.8

[qgrosperrin]

Installing clang did not fix the issue.
Thanks for the suggestion though!

I don't have hashcat installed on any other OS so I'll revert snapshots for now since the apt-get upgrade somehow broke the install. Previous version I had works fine.

In the meantime, if anyone else has suggestions let me know.
