[mapserver-users] free() methods in MapScript, compatibility MS 5.x and 6

[Armin Burger]

I used a script creating 3 different type of objects without applying 
the "free" method, put it in a loop with 1M cycles and opened it in a 
browser. Checking the memory usage of the Apache process while running 
the script showed no increase of memory at all. So I would guess the 
free() is not needed any more. Test was made with MS 5.6
