shut up a silly -Wmaybe-uninitialized warning

I understand why the compiler would complain about this
'maybe-uninitialized' variable (it's always initialized when used)
but I don't understand why the warning suddenly occurs while the
variable have already been dereferenced several times; But well ...

Initialize it with NULL to shut up the warning.
