Why is CGAL less stable on Ubuntu 20.04.5 compared to Windows? #8471

Open lisir3000 opened 2 months ago

lisir3000 commented 2 months ago

We implemented an incremental topological map application using the CGAL library’s Arrangement_2, Arr_segment_traits_2, and Arr_observer. We found that the library is more stable in a Windows environment. When running on Ubuntu 20.04.5, crashes occur, such as when inserting multiple overlapping segments into the library or when batch deleting vertices. These operations perform well in the Windows environment, but cause crashes in Ubuntu 20.04.5. Both environments use the same CGAL version 5.5.3. What could be causing this issue?

What gcc version are you using? Could you try clang++ instead?

That is really hard to guess without knowing more about those crashes. Are they assertions/exceptions that are thrown, segfault? Do you have stack traces?

CGAL-5.5.x is tested every week. See last test results. We do not test with Ubuntu 20.04, but we could. As Sébastien said, it is very important we know which compiler (and which version of it) you used.

By the way, you mentioned CGAL-5.5.3. Note that CGAL-5.5.4 was released in February 2024. Maybe that version already contains a fix for you issue. Could you try, please?

Also, what kernel are you using?
