In September 2004, open_dump_file was changed so that it aborts when a dump file is already open. That made the sh64-elf compiler abort when running with -da. I've fixed this with this patch: http://gcc.gnu.org/ml/gcc-patches/2005-01/msg01467.html -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=11375
