#58161 0x00005555557b0038 in ?? ()

58161 stack frames indicate a problem with a recursive call that crashes with a stack overflow. 

I built the attached file with an Umbrello application using Umbrello source version 25.08.2 and loaded from the git master branch, and I was unable to reproduce this error when loading the file.

It would be helpful to know what interactions with the application were performed before the crash and to obtain the Umbrello version used (Help->About menu). 

> No symbol table information available.

Obtaining a stack trace with Umbrello and Qt symbols (debug packages) installed would be helpful, as it would allow us to see more precisely where this is happening.

Code generation is working correctly, crash when adding a generalization, deleting it and re add a new one in the opposite side.

Umbrello UML Modeller
Version 25.04.2 (Applications 25.04.2)


Hi, thanks for the quick response, I have add a new file v3.xmi wich leads me to the same crash.

Reproduce steps : 

- Load v3.xmi
- Add a generalization from visitor to administrator (arrow pointing to administrator)
- Generate java code
   |-> [Working]
- Deleting it by selecting it and pressing "delete"
- Re-add a generalization from administrator to visitor (arrow pointing to visitor)
- Generate java code
  |-> [Crash]

I will upload the backtrace with debuginfod enabled as soon at it's download and generated

Backtrace with debuginfod

Here his the backtrace with debuginfod.

Tell me if there anything you need.

I have used my command like this to generate the backtrace :

gdb -ex "set debuginfod enabled on" -batch -ex run -ex "bt full" -ex quit --args umbrello5 > umbrello-backtrace.txt 2>&1

Fix bug not deleting uml association

When an association widget is deleted, the associated UML
association is not deleted. The remaining associations
are no longer visible because they do not appear in the
property dialog of a class. Since they are no longer
visible, cyclic inheritances can easily occur, which
can lead to a crash, e.g., of the Java export.

After this fix, it is important to restore the missing
widgets for such associations and to point out cyclic
inheritances when loading files.

Mark selected associations on the “Associations” page in the diagram

When you select an association on the “Association” page of
the class properties dialog, it is marked in the diagram so
that it can be identified.
