Ben,
I'm using prcExplorer to see the size of the data segments. When I look at the data block using prcExplorer there is a 0 and a 1 segment. In the version that is correct the 0 segment shows a size of 10573 bytes and the 1 shows 58744. It is very similar to show the various code segments appear as 0, 1, etc.
When I did the diff these are the only lines that differed, once I grepped out all the differing file names and some address offsets.
In good file: Data section below A4: 32768 bytes Data section above A4: 5870 bytes
In bad file: Data section below A4: 32768 bytes Data section above A4: 11236 bytes
I'm definitely getting an error on this dragging the .prc into the Simulator.
One other piece of info I saw a large global, ~6K, that I changed to an allocated struct that I had expected would change something for the better but there was not change in either version? Something isn't right. Maybe I should blast the Data folder again?
I'd be happy to give any more info or try anything that may help.
Thanks, -Mike

Are you looking at the size in the map file or in the project view?
First, there is no "data segment 1". There's only one data section used by
the whole program, and all the data that's attached to the different code
sections is aggregated into the one data section.
Second, the value in the project window are maximums. This is the value
emitted by the compiler -- the linker strips out anything that isn't
referenced, so that value will always be lower in the actual program.
I'd make map files (see 68K linker panel) on both systems, then use CW's
diff engine to compare those and see if something is setup differently.
