It seems that the call to `abort' has been here forever, as `cvs
annotate' reports:

1.1          (green    06-Sep-98): void
1.1          (green    06-Sep-98): insert_block (block)
1.1          (green    06-Sep-98):      tree block;
1.1          (green    06-Sep-98): {
1.1          (green    06-Sep-98):   TREE_USED (block) = 1;
1.1          (green    06-Sep-98):   abort ();
1.1          (green    06-Sep-98):   current_binding_level->blocks
1.1          (green    06-Sep-98):     = chainon (current_binding_level->blocks, block);
1.1          (green    06-Sep-98): }

Most likely, but I don't see anything obvious in the ChangeLogs
mentioning such a thing. I can try to reproduce the problem. Or, since
the problem occurs on your configuration, you can try to use gdb to
see what's going on by reproducing the invocation of jc1 on
`Connection.java', under the control of gdb. Can you do that for me?

Thank you,
