Forgot to add Signed-off-by - corrected patch follows -

Variable goal_eloc is automatic, non-static and initialized conditionally.
 The following patch fixes this by initializing the goal_eloc variable to zero.
Hopefully zero should be better than some random data! (Patch also
attached in case of problem with below inline version.) Compile
tested.
