My Eiffel program (or system!) has suddenly developed segmentation faults
which appear in apparently unrelated places as I make changes in a vain
attempt to track the problem down.  Precondition checks are on so the
Unix segmentation faults are not simply as a result of overlooked void
references in the Eiffel code.  Presumably the problem is something to
do with the compiler or run time system.  The faults appeared shortly
after I started using the ENVIRONMENT class to store objects (but not
immediately afterward).

Does anyone at ISE or elsewhere know what the problem might be?  We
run Eiffel V2.2B on a Sun 4 Sparc server.
