Not the same problem, but something that may be quite similar.
Yesterday I encountered a problem with the "disk: No disk found."
message.  Well, not with the message per se, but with not finding
any disks.  In this case, 8xxrom still tries to prompt you, but the
file_cwd (I think - this was about 24 hours ago) was not set, so
the prompt tried to print "rom:0:              "  with the spacing
continuing on for several lines until the machine crashed.
And, I am using egcs-2.95.2 to compile for my 850.
