Summary:                    printf reads uninitialized memory
Description: 
Hello, here is a test case that leads printf to read uninitialized memory:
./printf "%Ld\n" 10
39860182724902922
(output varies, since it reads garbage)

The problem is that this execution eventually invokes libc's printf with 
the same format specifier, and with the second argument my_xstrtol("10"). 

This returns a long (4 bytes on my machine), which is printed as a long
long 
(8 bytes on my machine).  Unfortunately, I don't see an easy fix here, 
because most conversion routines in Busybox seem to return longs.
