OpenDRIVE parser rejects valid vertical roads

[Syed-Abbas-Hussain]

Description

AVLite fails to load exactly vertical OpenDRIVE roads. Consecutive points on a vertical road have the same X coordinate but different Y coordinates.

The parser checks only X:

assert x_vals[-1] != x_vals[-2]

This incorrectly treats valid 2D points as duplicates.

Error

File "c18_hdmap_parser.py", line 511, in sample_OpenDrive_geometry
    assert x_vals[-1] != x_vals[-2]
AssertionError: last two points:
3.0000000000000018, 3.0000000000000018

I attached the .xodr HD map that reproduces the error in the comments below.

You can try OSC2 Studio — it also has a map preview feature. I've tested it and it works fine with your map file. Just visit https://osc2studio.online/ in your browser, add your map file to the workspace on the left, then double-click it and the preview will appear on the right.
