behavior_velocity_planner sometimes crashes before intersection

• I'm convinced that this is not my fault but a bug.

Description

Yesterday, during test drive on private site, I observed behavior_velocity_planner crashes often when approaching an intersection. The crash cause is always an out-of-bound access input_path.points.at(stop_line_idx) here:

autoware.universe/planning/behavior_velocity_planner/src/scene_module/intersection/scene_intersection.cpp

Lines 161 to 163 in 6247671

	setDistance(tier4_autoware_utils::calcSignedArcLength(
	input_path.points, planner_data_->current_pose.pose.position,
	input_path.points.at(stop_line_idx).point.pose.position));

Expected behavior

No crash

Actual behavior

crash

Steps to reproduce

1. Run behavior_velocity_planner on a lanelet map with intersections (manual driving is ok, simulator maybe too)

Versions

• Ubuntu 20.04
• galactic
• private fork of main

Possible causes

To dig further, I recompiled behavior_velocity_planner module in Debug mode and ran it with gdb. Here is the full backtrace when the crash occurs:

The problem is obvious when the you look at the variable state:

• stop_line_idx is 81
• input_path, which is a copy of original path, has 81 points (so input_path.at(stop_line_idx) is out-of-bound)
• path, which has been modified, has now 82 points

The stop_line_idx is initialized here, and seems to be only suited for path and not input_path:

autoware.universe/planning/behavior_velocity_planner/src/scene_module/intersection/scene_intersection.cpp

Lines 127 to 133 in 6247671

	if (!util::generateStopLine(
	lane_id_, conflicting_areas, planner_data_, planner_param_.stop_line_margin, path, *path,
	&stop_line_idx, &pass_judge_line_idx, &first_idx_inside_lane, logger_.get_child("util"))) {
	RCLCPP_WARN_SKIPFIRST_THROTTLE(logger_, *clock_, 1000 /* ms */, "setStopLineIdx fail");
	RCLCPP_DEBUG(logger_, "===== plan end =====");
	return false;
	}

A simple fix is to get rid of input_path and replace it by path, however I am not sure it is the correct solution. The code logic is beyond my understanding.

@VRichardJP
Thank you for your report.
I agree to replace input_path to path.

[VRichardJP]

So should input_path be replaced everywhere by path or should it keep it at other places?

@VRichardJP Could you confirm that this issue is resolved by #1283

[VRichardJP]

Yes, I tested the same modification during my test drive session and I haven't faced the issue since.
Thank you!
