CCS v5.3 error reading 'used' flash in map file

MSP430FG4618 uC

I just switched a project from CCS v4.2 to v5.3

In v4.2 there was ~4kb of used flash memory.

With the same processor and code in v5.3, the used flash memory reads 14,254! (Unused 0x96b2)

I note that at the top of the map file: MSP430 Linker PC v4.1.5

Is there a different way to read flash in v5.3?  Or, is there a known bug?

Thanks in advance!
