При этом именно приблизился, поскольку, как видно из MAP файла остается еще 0x156 байт в заполняющем сегменте. Содержимое бинарника соответствует листингу :-) - свободное место есть.
Если убрать CHECKSUM, то бинарник естественно получается менее 8K на 0x154 байта.

Однако, если теперь добавить хоть один байт, линекр сразу вылетает с воплем:
Error[e16]: Segment CHECKSUM (size: 0x2 align: 0) is too long for segment definition. At least 0x2 more bytes....

У кого есть мысли, что это такое????
