[Cownie, James H via Openmp-dev]

I see one bug there, for sure.

The LLLVM runtime shouldn’t be pointing you at Intel support!

Hi Mohammad,

moving this to openmp-dev as you mention an assertion in the OpenMP runtime (questions about the compiler should go cfe-dev instead of llvm-dev).

I just tried reproducing the issue on my system and was able to run all binaries built with Clang 3.9.1 and the latest trunk of the OpenMP runtime in Debug mode. (I had to increase OMP_STACKSIZE for UTS, otherwise it kept crashing)
Which benchmark do you have problems with and which environment variables do you set? Is there anything special about your setup?

Regards,
Jonas

Hi everyone,
I would like to execute OpenMP applications in BOTS benchmark with clang 3.9.1 but I get the following error:
Assertion failure at kmp_tasking.c(421): taskdata -> td_flags.tasktype == 1.
Assertion failure at kmp_tasking.c(439): taskdata -> td_flags.started == 0.
OMP: Error #13: Assertion failure at kmp_tasking.c(421).

Any help is highly appreciated!
Thank you and best,
Mohammad
