Summary0010651: Uninitialised bytes written when saving newly generated world.
DescriptionRunning DF under Valgrind I generated a pocket sized non-custom world, with all other parameters left at default. There were no error messages up until I accepted the generated world at 250 years, at which point Valgrind reported one "Syscall param writev(vector[...]) points to uninitialised byte(s)" and one "Syscall param write(buf) points to uninitialised byte(s)".
Additional InformationThe relevant Valgrind output:
