Normally, one would expect to find two lines like the above 2 but
with 11535 replacing 3380.

Can you redo the experiment with
   valgrind -v -v -v -d -d -d ....
then do 
   ls -l /tmp/*xxxxx*
   (replace xxxxx with the process id as found in the valgrind output)
   (this ls command should show files such as the above)
and then re-do the vgdb -d -d -d help
  If the ls command does not show anything, then the valgrind debug log
  should indicate a trace related to deleting these files.

Thanks
