Ho hum. I rebuilt a stage1 egcs (with the stage0 egcs which i'd compiled with 184.108.40.206+myc1). Now that exhibits the same symptoms Castor Fu described. Ghastly. I'm rebuilding stage0 egcs libcc1.so and cc1 with 220.127.116.11, just to be absolutely sure. (with my luck it'll be the libcc1.so from Sep 29 which makes the difference :-<).
