Hi together,
I have an algorithm whose results incl. the graph I save to disk at the end.
When I load it again, on some vertices, shortest_distance() crashes python:
```
munmap_chunk(): invalid pointer
Aborted (core dumped)
```
Any ideas on how I can debug this?
All the property maps are internal and my custom vertex lists are converted to int before pickling and restored using gt.Graph().vertex() afterwards.
Thank a lot for ideas!
Cheers,
Stephan
