Error: File name too long

Again, thank you for creating this wonderful tool.

I am try to run perftool in the default profile analysis mode. I know this code well and it should be memory bound. In particular, it should be bound by the bandwidth at the LLC.

Here is the script that I set-up.

#!/usr/bin/bash
bin=$HOME/miniAMR/ref/miniAMR.mpi.x.icelake
args='--num_refine 4 --max_blocks 1000 --npx 2 --npy 2 --npz 2 --nx 8 --ny 8 --nz 8 --num_objects 1 --object 2 0 -1.71 -1.71 -1.71 0.04 0.04 0.04 1.7 1.7 1.7 0.0 0.0 0.0 --num_tsteps 100 --checksum_freq 1 --report_perf 1'

spack load mpich target=icelake

perf_do=$HOME/perf-tools/do.py
${perf_do} profile -a "mpirun -np 8 ${bin} ${args}" --tune :calibrate:1 --perf $HOME/perf-tools/linux-5.15.111/tools/perf/perf

It appears to get through the first level of analaysis, but then runs into a ERROR:
