[9.0b17x86, rc2] Crash in compare and edit

[MVV]

I don't know if this bug exists in 9.0rc2, I can't reproduce it. I compared local file with file in archive and switched to edit mode in order to insert line from archived one into local one. It was necessary for me to insert that line into the middle of local file so I inserted empty line in local file and then inserted new line with some random characters in archived one in order to resync comparison from previous line in local file (just between inserted new line) and first line in archived one (before needed line), and when I've confirmed resync with erasing undo history the bug have happened...

Steps:
1. Compare TC's history.txt (make a copy) with test file 1.txt (any one-line file, I've copied a line from keyboard.txt into it).
2. Insert a new line into history.txt (I've inserted it at index 30) and recompare files (save changes).
3. Insert new line at the beginning of 1.txt and type some random characters into that line (I've typed qwerty).
4. Select some typed characters in 1.txt (I've selected wer) and some characters from the line before inserted empty one (I've selected ey from key word) of history.txt and resync comparison from selected lines.
5. Sometimes I can't reproduce it from first try so I remove new line from 1.txt and recompare files, and then repeat steps 3-4.

Thank you, Christian, seems to be fixed in 9.0 RC3!
BTW I've noticed that you've mentioned "synchronize dirs" in corresponding history line instead of "compare by content":

25.10.16 Fixed: Crash in synchronize dirs after edit, re-compare (with save), edit, then "recompare from here" (32/64)
