Level-zero zello-world - Abort

[jjfumero]

I am running level-zero from:

intel-llvm/llvm/build/tools/sycl/plugins/level_zero/level_zero/level_zero_loader

I am using GCC 9: gcc (GCC) 9.3.1 20200408 (Red Hat 9.3.1-2) on CentOS 7.8

When running the zello-world example, I get an abort:

Abort was called at 102 line in file:
/builddir/build/BUILD/compute-runtime-20.41.18123/level_zero/core/source/cmdlist/cmdlist_imp.cpp
Aborted (core dumped)

However, If I build level-zero using this repo:
https://github.com/oneapi-src/level-zero/tree/master/samples/zello_world

I don't get any abort.

This is the backtrace I get by using gdb:

$ gdb ./zello_world -c core.file
 
Core was generated by `./zello_world'.

Hope this helps.

Hi @jjfumero
I think you can get more luck reporting this bug to https://github.com/intel/compute-runtime

[jjfumero]

@alexbatashev , this issue is now solved here: intel/compute-runtime#377

The version provided in intel/llvm was deprecated.
