Ron KLINKIEN reported a new bug.

Summary
-------

Crash of 3.9.1 IDE while editing code

Type             : Bug
Priority         : High
Gambas version   : 3.9.90 (TRUNK)
Product          : Development Environment


Description
-----------

While creating new code I crashed my IDE while deleting some bogus code.
I seem te be able to reproduce it.

Open attached project, go to code view of FMain, place cursor between run and () and type backspaces to delete the run word and the space in front of it. 

This application has raised an unexpected
error and must abort.

[21] Out of bounds.
