additional unwanted signs in stdout after sucessfully loading a string

Both example show the problem that we can successfully call the strings with near and far progmem-getters, but after the string 142 is send, there are a few dozen unwanted additional non ascii signs put into stdout. The string is null terminated in flash, as you can observe by yourself with the target at the end of the CMakeLists with objdump.
