As I steer gretl towards a "stable" release (version 1.0) I welcome any reports of bugs in the program. I think you are unlikely to find bugs in the actual calculations done by gretl (although this statement does not constitute any sort of warranty). You may, however, come across bugs or oddities in the behavior of the graphical interface. Please remember that the usefulness of bug reports is greatly enhanced if you can be as specific as possible: what exactly went wrong, under what conditions, and on what operating system? If you saw an error message, what precisely did it say? (You needn't bother, though, to quote the memory address numbers given in any crash reports from MS Windows — these won't mean anything to me.)
