[Solved] Ticket #4191 - Crash on spreadsheet in-cell value edit

[ulrich1a]

The crash seems to depend also on the performance of the computer. I tested my model on a low end laptop. There it crashes between values of 6 or 7 mm for the "Radius" in the spreadsheet. The crash is sometimes delayed on this computer. The logfile contained these statements:

Code: Select all

Log: QObject::installEventFilter(): Cannot filter events for objects in a different thread.
Err: Illegal storage access...
Err: Unhandled Base::Exception caught in GUIApplication::notify.
The error message is: Illegal storage access! Please save your work under a new file name and restart the application!

I do wonder, if this crash will not be related to this one: https://forum.freecadweb.org/viewtopic.php?f=10&t=40806
It seems that in both cases the event handling of Qt is involved. I got the following in the log-file after a Ctrl-a:

Code: Select all

Err: Illegal storage access...
Err: Unhandled Base::Exception caught in GUIApplication::notify.
The error message is: Illegal storage access! Please save your work under a new file name and restart the application!
Log: The event type 6 was sent to Gui::TreeWidget

357.106 <App> Document.cpp(3462): Failed to recompute SpreadsheetCrash3#Pocket002: Pocket: Result has multiple solids. This is not supported at this time.

Code: Select all

Recompute failed! Please check report view.

These are the only two errors I see when changing "radius" to 12.

Is this the "crash" that is being described? My FreeCAD is still up and running, just seems to have an error.

Or is there a more serious crash that is being experienced on other platforms?

as an update: is it possible to duplicate the issue with the attached document?

I've tried to duplicate the file uploaded by ulrich, except using purely the Part workbench rather than the PartDesign workbench. I'm still relying on Spreadsheet references.

My reason for this is that some preliminary tests on my end suggest that the issue is not specific to Spreadsheet, but rather in PartDesign. This assumes the actual issue is as I've described in my previous post...
