Unfortunately while rvmx86lnx32b was off the air, we blew out the code image size by 25%, the data image by 5% and the gross by 10%
[1].
The revision window is r13822-13836. It looks like the only changes to the trunk in this window were a number of compiler changes, so presumably that's where the problem is (Dave & Daniel's changes were just to branches).
Ian, can you please take a look?
Thanks,
