The Program has stopped unexpectedly by raising signal #11

This message is displayed by the Development Environment when the running project crashes.

This is not a bug in your project, but a bug in the interpreter. This message should never occur, but nothing is perfect is this world!

What you can try before reporting the bug:

Check your Gambas version, and try to install the latest one provided by your distribution.
If you have already the latest version provided by your distribution, try to compile the version located in the source repository.

If everything fails, you ~~must~~ should report the bug, as explained on the Reporting a problem, a bug or a crash page.
