 I could not reproduce your error: I am using gcc version: `Apple  
 Computer, Inc. GCC version 1161, based on gcc version 3.1 20020420  
 (prerelease)'
 Also `Apple Computer, Inc. GCC version 1200, based on gcc version 3.3  
 20020824 (experimental)' (apple's Darwin -Head code).
 And `gcc version 3.3 20020911 (experimental)' (fsf cvs code).
 
 Thanks,
 Andrew Pinski
 
 I used the following program to test your function:
 int main()
 {
 	int i;
 	char  
 temp[]={0x11,0x11,0x11,0x11,0x11,0x11,0x11,0x11,0x11,0x11,0x11,0x11,0x11 
 ,0x11,0x11,0x11,0x11,0x11,0x11,0x11,0x11,0x11,0x11,0x11,0x11,0x11,0x11,0 
 x11,0x11,0x11,0x11,0x11};
 	ClearBlock(temp, sizeof(temp));
 	for(i=0;i<sizeof(temp)/sizeof(temp[0]);i++)
 	{
 		if(temp[i]!=0)
 			printf("%d\n",i);
 	}
 	return 0;
 }
