This command line just creates the object file.  What is the command 
line that you use to link the object file and create the map file ?

This certainly does appear to be a linker problem.

Can you put together a small test case to demonstrate the problem ?  I 
have tried using the information in your previous email, but I could not 
create an unaligned assignment for test1.  (ie I always found that the 
linker was aligning test1 on a 4 byte boundary, so there must be some 
difference between my test and yours).
