Resolution:
Modify the code to eliminate the redefines of the extension operator; then recompile.
Example:
In the following example, the operator definition redefines a binary-long type. This is not allowed.
class-id a static. operator-id + extension (i1 as binary-long, i2 as binary-long) returning ret as binary-long. set ret to i1 + i2 end operator. end class.
