Hello ROOTers,

The line
56: can->SaveAs("tmp.png");
in "test2.cxx" causes a memory leak if I run the program as a daemon process on SL 4.4. You can see that heap memories are deleted in the end of while loop in the code. But memory leaks happen.

$ cd /home/foo
$ ls

testd test2.cxx
$ g++ -c -o test2.o test2.cxx `root-config --cflags`
$ g++ -o test2 test2.o `root-config --glibss`
$ su

# mv testd /etc/init.d
# /sbin/service testd start

Starting test2:                        [  OK  ]

# exit
$ PID=`pgrep test2` top -p $PID

You will see the used memory increase. How can I eliminate this problem?

Sincerely
