Plainly not.  But suppose Bob takes Alice's program under the GPL and
and adds a bunch of calls to syslog() so that it logs what it is doing
(and suppose further that this is not a de minimis or merely mechanical
change).  Do you then hold that this is not a derivative work either,
and therefore need not be licensed by Bob under the GPL?  After all,
it is not as if you can't trace every single bit in the source code or
resulting object code to Alice or Bob respectively, at least assuming
the compiler is not over-clever.
