- Notice that the value returned by `fstat(0, ...)' indicates that /dev/null in
your system is a *regular* file (it should be `st_mode=S_IFCHR|0666', but
instead it is `st_mode=S_IFCHR|0666'). It also indicates that its size is 73
bytes (`st_size=73').
- Notice that `cat' reads from file descriptor 0 (i.e. /dev/null), and the
return value is a string of 73 bytes in length.
- `cat' then writes that string out to `./config.status'
73 happens to be the length of the string that has been causing issues for you:
$ echo "extern void free (void *__ptr) __attribute__ ((__nothrow__ ,
__leaf__));" | wc -c
73
This is a first-class observation.
