6.6.11.6 -fpack-struct

Pack all structure members together without holes. Usually you would not want to use this option, since it makes the code sub-optimal, and the offsets of structure members won’t agree with system libraries.

The dsPIC^® DSC device requires that words be aligned on even byte boundaries; so, care must be taken when using the packed attribute to avoid run time addressing errors.
