ccs6 od long long problem or bug in debugger

possible bug in ccs compiler

i use the test code
signed char actal[8]; memset(actual,0,8); actual[7]=-127;

unsigned long long a= (unsigned long long)actual;

the contend of a reads(debugger) Hex:0x0000000020021AF8
 where                                                  hex 0x8100000000000000 would be expected

most troubling
as
if ((unsigned long long)actual==0x8100000000000000) Report("\n\rmatch the hit\r\n "); does not print as ok

does not print as anything.... i must do something wrong......

I need a good weekend anyway ....

all help apreciated
