Comment 6 Jim Raykowski 2022-11-04 05:45:04 UTC
Hi All,

This is a difficult one to bisect due to a bug during a period in 7.2 when outline folding is on that causes a crash when delete is pressed. I turning off outline folding to bisect, Menu > Tools > Options... > LibreOffice Writer > View > uncheck 'Show outline-folding buttons'. I never got a hang on delete in 7.2 but did run into an X being placed across image94 on the third bisect and later in the bisect process no X but also no delete. 

My bisect effort came up with this in 7.2:

    tdf#59463 track changes: record deletion of images   
    
and in 7.3

    tdf#142701 track changes: fix layout regression of image deletion


I stepped through the code and saw that the hang occurs here: 

SwWrtShell::DelRight 

Insert( OUStringChar(CH_TXT_TRACKED_DUMMY_CHAR) +                            OUStringChar(CH_TXT_TRACKED_DUMMY_CHAR) );

https://opengrok.libreoffice.org/xref/core/sw/source/uibase/wrtsh/delete.cxx?r=70973680#475   
    
I always get expected results, image deleted, no hang, when Track Changes is turned off, Menu > Edit > Track Changes > Record unticked.

It seems, no problem with version 24.8. Do we need a fix for 24.2?
