This abort occurs when computing a GC bitmap descriptor of a class. What it means is that we think we've seen overlapping fields in the class -- which is a "can't happen" in java. It might help if you could run gdb on jc1 and see the values of 'offset' and '*last_view_index'. Based on the test case and the location of the abort I would say that, for some reason, the implicit 'this$0' field in Three is somehow overlapping the fields inherited from its superclass. -- tromey at gcc dot gnu dot org changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |tromey at gcc dot gnu dot | |org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=26042
