Summary: Output references undefined label

Initial Comment:
Generated assembler code reference label _00293_DS_,
but it's not defined.  The workaround if it can be
called that, because it changes the logic is to insert
a break statement.  Search for "COMPILER_BUG" to see
where the break statement needs to inserted.  When that
break statement is added the warnings about
"conditional flow changed by optimizer" go away too, so
maybe it's an optimizer bug.
