It means that the interpreter crashed. This is not your fault, it is a bug in 
the Gambas interpreter or compiler.

When a program executes illegal code, the Linux kernel send it a "signal" to 
warn it about that, just before stopping it.

This signal has the number 11, and there are many others. Type 'man kill' in a 
shell to learn more about them.

No, this is a success if you can reproduce the crash. This mean that it will 
be easier for me to debug and fix it!

Send me your project. If it is too big, just remove all unneeded data files 
(sounds, pictures), or replace them by smaller ones. There is very small 
probability that these files cause the crash.
