Dear developers and the rest of the community

Thanks for your effort on the accel-sim toolchain!

I recently downloaded the accel-sim framework and got the SASS traces using get-accel-sim-traces.py.

I tested the tool for a specific workload. And here is the command I used.

However, I encountered a segmentation fault. Here is the error message.

It seems like the segmentation fault happens right after L1 cache reconfiguration. Does any developer encounter similar problems?

Thanks so much for your time!

Best

Thanks for your prompt reply! I'm using GCC 9.3 now, and I will try it with the older version GCC. Thanks again!

Hi everyone

It seems that GCC 9.3 is not the issue. The tool runs smoothly when I set_environment to debug mode.

Thanks for your help!
