This bug was filed from the crash reporting server and is
br-0d03b39b-2925-4468-b67c-52cf6437ea41.
=========================================

Just a normal operation crashed the program and I don´t know if it belongs to
my old system (i7-4770  8GB RAM).

I changed the way how I calculated something. 

I made a new simple formula (see attached sceenshot)  +L73+T74 [in this cell].
As I copied this for the next 500 cells (down to L560) the program shut down,
which was/is reproducable. I did it again in short steps of ~20 rows now. At
the end I recognized, I forgot to change the last cells in column T [which
maybe caused the program crashes as I copied the cells over this line]. I
filled this column some numbers, but in the last ones there were the old
formula. So that the construction in the last rows was

in cell L546 (and all below):  L545+T546

in cell T546 (and all below):  L546-L545


There are a lot of other operations done with the numbers of this two columns
on the whole sheet.

It worked as I copied one row after another. Then came an error:522. So the
problem maybe only occure when I copied _some_ rows below the
conflicting-operation-line. 
This is btw. not the first time I recognize similar copying-problems within in
the last year. I don´t know if my system is just bad.
