[Fixed] Ticket #4230 - FC 0.19.18946 crashes on second edit of Chamfer @ Part-WB

[lutz_dd]

I'm getting pretty reliable a crash if a chamfer is edited a 2nd time in the current session while ignoring "... restart the application" in the ReportView. My setup is clean after fresh installation with the old directory App/Roaming/Freecad renamed.

My previous version FC 0.19.18760 from Nov/18th/2019 does not express this behavior.
Latest version FC 0.19.18990 from Dec/18th/2019 is still having this issue.

How can I get rid of "Illegal storage access!" ?

Procedure
Start FreeCad ...
Edit/Preferences
. . . change Language to "English"
. . . The ReportView returns . . . "Failed to load UI file from ':/ui/preferences-dxf.ui'"
File/New
Change WB-Start -> WB-Part
Part/Primitives/Cube
Part/Chamfer...
. . . Select Edge1
. . . Press OK
Select the "Chamfer" in ComboView/Model-Tab
RMB (RightMouseButton) over the "Chamfer" ... choose "Edit chamfer edges"
. . . Press OK
. . . The ReportView returns . . . Illegal storage access / <Exception> Illegal storage access! Please save your work under a new file name and restart the application!
RMB (RightMouseButton) over the "Chamfer" ... choose "Edit chamfer edges"
. . . Press OK
. . . Crash

Sort of confirmed here on MacOS too: It crashes already on first edit. This worked with 0.19.18846.

Once "Illegal storage access!" occurs in the ReportView

• Save file, close all TAB and re-open the File ... crash.
• Save file, close FC and start FC again, edit once more chamfer edge, save, close FC ... no crash, can be repeated many times

It seems the issue is not going into the file.

Will file a bug.

The same bug is present if the Fillet tool is used instead, both with version 0.19.18990 and 0.19.19060, but not in 0.19.18842.
I added a note and fillet tag to the bug tracker report.
