Summary0004378: Crash after changing a pocket-size
DescriptionCrash after changing a size-parameter in a sketch and close sketch (cpu gets 100% load and memory runs full)
I am not sure if ths issue is found before as I do not know how to name it.
But on my PC it is very simple to reproduce.
Steps To Reproduce1) open RegalBuero (copy).FCStd
2) change WS to part-design
3) open last sketch043: RegalBuero/P2_KeinteilBoxen../B8_BodenHinten001/Seitenloecher/Sketch043

4) In this sketch043 change the very right-side hight-parameter from 32,8 to 33mm
5) close the sketch
6) look on cpu and RAM. On my PC CPU become 100% load (after aprox 5sec) and RAM starts slowly overflow (approx 30sec left until complete overflow)

Additional InformationI use appimage file.
If size of hight-parameter is less than 33 mm, no problems occur. 33mm and bigger seems to be a problem which is not catch in code.
I created this 3d-model last week and updated appimage-version 1 time. With current version of FreeCad and at least one version before the issue occurs on my PC.
Hope you can reproduce it on your PC.

Hm, looks like I do something wrong at adding the file. Filesize 1,6MB. No error. Green bar under file.

But when I go over the attached file is says:
html> <head><title>413 Request Entity Too Large</title></head> <body bgcolor="white"> <center><h1>413 Request Entity Too Large</h1>

I already removed most parts of the model. Is there a different way to add the file?

Tried to create a forum thread. But here an error comes when trying to add the file.
(see screenshot)
But without file, it does not make sense to talk about (Description: On Increasing a pocket size, computer crashes??? ).
Is there a possibility to send you the model?
