The error is stably reproduced in "Calc" in the "Print Preview" mode when the cursor moves over the viewing area.

Possible growth place of an exception:  https://cgit.freedesktop.org/libreoffice/core/tree/sc/source/ui/view/preview.cxx?id=0ad8447d3199e1c1d1f7d6ddabc9b4cded99c2d6#n1359 
Perhaps "mvRight" was not initialized before calling "ScPreview :: MouseMove", as here:  https://cgit.freedesktop.org/libreoffice/core/tree/sc/source/ui/view/preview.cxx?id=0ad8447d3199e1c1d1f7d6ddabc9b4cded99c2d6#n434
Comment 5 Julien Nabet 2017-10-25 07:01:53 UTC
Noel: couldn't nRight/mvRight have a fixed size to MAXCOL+1 and so what about using http://en.cppreference.com/w/cpp/container/array ?
Comment 7 Noel Grandin 2017-10-25 13:48:46 UTC
the intent of the commit was to avoid allocating more columns than we actually need, since we intend to raise the column limit
Comment 8 Julien Nabet 2017-10-25 21:32:01 UTC
Noel: ok then, I understand better.
