Don't split snowmen!!! How dare you?
More seriously, the difference to #1022 and #1036 is that @hroncok seems to be using 1.37 and not 1.36. The backtrace shows the more or less obvious: the crash seems to happen while drawing the indicator in Scintilla. It might be there is a bug in the start to end calculation for the indicator.
Unfortunately, I cannot reproduce it :(.
