Description

I followed the MoveIt benchmarking tutorial for Noetic step by step to learn about the benchmarking tool, but I got an error when running the benchmarks by launchin​g demo_panda.launch containing the moveit_run_benchmark node. I later traced the error using GDB, and the error seems to be caused by a std::vector access out of bounds in the call to moveit_ros_benchmarks::BenchmarkExecutor::runBenchmarks. For comparison, I followed the benchmarking tutorial on Melodic (with MoveIt 1.0.8 installed ) and did the same thing and it worked without problems and benchmarking ran successfully. So is this an error caused by some bug in MoveIt 1.1.7?

Your environment

• ROS Distro: Noetic
• OS Version: Ubuntu 20.04 (kernel 5.11.0-40-generic)
• Binary build
• MoveIt 1.1.7

Steps to reproduce

roslaunch moveit_ros_benchmarks demo_panda.launch

Expected behaviour

generate benchmark log files

Actual behaviour

Thread 1 "moveit_run_benc" received signal SIGSEGV, Segmentation fault.
