Python Issue- tracer internal crash at PC 0x00007f1c604c8990

Created by: arkodutt

While trying to run an example python executable operating on alexnet with bin64/drrun -t drcachesim -use_physical -- python ../alexnet.py, I encountered the following error [although this error could have been lodged onto another issue]:
