Well, I am not Bugzilla nor the all-knowing garbage dump ... ;)

This could be, but I am not really sure ... :( If I start
<quote>
gdb soffice.bin | tee HeadingUndoCrash.log
</quote>
, I get a crash as well, but LO's UI seem to be O.K., until you try 
to move the cursor ... ;)

Was it not possible in the past to start LO with "-debug" or "-gdb" 
or something like that? The only still functioning (but not 
documented) parameter is "-strace" ... ;)

O.K.

Oh, interesting. I was testing a bug about changing headers to 
numbered headers, when I discovered the crash ... Your test 
procedure is much shorter ... ;) This evokes old OOo days, when a 
former team member was mentioning, that he found a way to crash OOo 
with one click (or so) ... ;)

Thanks for your info and your further tests (and explanations as 
well) :)
