Summary: SDCDB (from package of SDCC 2.5 and all CSV) works badly.  

Initial Comment:
SDCDB (from package of SDCC 2.5 and all CSV) works badly.  

1: Sample code that reproduces the problem.
This is only test program but described problem is for
all programs I have tested.
;test.c
int x=0;
void main(void) 
{ 
	while (x<100)
	{ 
		x += 1;  //line no. 7
	} 
} 

 2: Exact command used to run SDCC on this sample code.
sdcc --debug  test.c
sdcdb test

 3: SDCC version tested.
SDCC :
mcs51/gbz80/z80/avr/ds390/pic16/pic14/TININative/xa51/ds400/hc08
2.5.1 #1043 (Jun 17 2005) (UNIX)
But I have the same result for all versions of SDCC 2.5.x.

 4: Copy of error message or incorrect output.

It works fine.
