Howdy,

	The following twisted program seems to trip a bug in cfront 2.0.  Does
anyone know if this is fixed in 2.1?

	thanks,
	
		Doug

----------------------------------------
extern int foo (void);

int a = 100;
int i = 10 + foo ();
int j = i + *new int (1);

foo ()
{
	static int k = foo ();
	return 100 + a;
}
----------------------------------------

	Here's the result of compiling with CC:

	% CC t.c
	"t.c", line 5: k undefined

	And here's the mangled cfront code:

----------------------------------------
CC -F t.c
#line 1 "t.c"

/* <<AT&T C++ Translator 2.0 06/30/89>> */
/* < t.c > */

#line 1 "t.c"
char *__vec_new ();

#line 1 "t.c"
char __vec_delete ();
typedef int (*__vptp)();
struct __mptr {short d; short i; __vptp f; };

#line 1 "t.c"

#line 3 "t.c"
int a = 100 ;

#line 1 "t.c"
extern int foo__Fv ();

#line 4 "t.c"
int i = 0 ;
int j = 0 ;

#line 1 "t.c"
int foo__Fv ()
#line 8 "t.c"
{ 
#line 9 "t.c"
static int __1k ;

#line 10 "t.c"
static int __0__F2 ;

#line 9 "t.c"
__0__F2 ?0 :( (__1k = foo__Fv ( ) ), (__0__F2 = 1)) ;
return (100 + a );
}

#line 1 "t.c"
extern char *__nw__FUi ();

#line 13 "t.c"
char __sti__t_c_a_ ()
#line 4 "t.c"
{ 
#line 4 "t.c"
int *__0__N1 ;
i = (10 + foo__Fv ( ) );

#line 5 "t.c"
j = (i + ((*( ( (__0__N1 = (((int *)__nw__FUi ( sizeof (int )) ))), (((*__0__N1 ))= k )) ,
#line 5 "t.c"
__0__N1 ) )));
}

#line 13 "t.c"

/* the end */
