[BUG] cudaErrorIllegalAddress

[Gorniker]

Hello, I'm encountering an almost persistent (9/10 runs) cudaErrorIllegalAddress error running vehicle routing optimization. According to logs, it happens at "compute_insertions.cu" line 875.
The error occurs both with initial_solution and without one. It also remains with CUDA_LAUNCH_BLOCKING=1.
I got the same error on 2 different servers.
Environment:
1)NVIDIA GeForce RTX 4090 (24GB), driver 570.133.20
2)L4, driver 575
CUDA: 12.8
cuOpt: 25.05
Python: 3.12.3
Memory Usage: ~1.4GB/24GB when error occurs

Data files are attached.

Hi @Gorniker, thanks for submitting the bug!
We have provided a fix for the initial solutions. I have checked the json with initial solutions. It appears that you have an incomplete solution. We expect the pickup-delivery pairs to be inserted. In your solution one of the nodes is missing it's brother.

You are absolutely right, thank you. Here's the correct initial solution, in case it helps.
