------- Comment #3 from pinskia at gcc dot gnu dot org  2009-11-19 15:31 -------
Compiling with -W -Wall, we get the following warnings:
t.c: In function ‘main’:
t.c:9: warning: format ‘%d’ expects type ‘int *’, but argument 2 has
type ‘unsigned char *’
t.c:11: warning: format ‘%d’ expects type ‘int *’, but argument 2 has
type ‘unsigned char *’


Those warnings show that this code is undefined,
