I can confirm this on windows.
It seems to be the ToDoListView that crashes.
Can you please try it with ToDoList-plugin disabled ?

Can anybody, who gets the crash, test the attached patch.

The cause for the crash seems to be the headerguard at the last line, which has a comment, that starts with NOTE (a keyword for the todolist), and the fact, that there is no line after it, so there is no linefeed (or carriage-return) and the plugin tries to read beyond the buffers length.

Met much trouble, if each plugin has CBP project would be better!

Luckily, all resolved.

Jens's Patch seemly resolve the crush problem.
