Did you try reading the documentation?
When an object is traced any copying of the object by the C
function ‘duplicate’ or by arithmetic or mathematical operations
produces a message to standard output. The message consists of
the string ‘tracemem’, the identifying strings for the object
being copied and the new object being created, and a stack trace
showing where the duplication occurred. ‘retracemem()’ is used to
indicate that a variable should be considered a copy of a previous
variable (e.g. after subscripting).
