Strange.  I don't see any obvious candidate.  Suggest to bisect.  From
12 MB to 40 MB sounds a lot to me, I cannot even begin to think what
kind of change could cause that.  Did anything change on your build
system since then?  Did you move the source tree to a different place,
perhaps (file names are recorded in the dumped data, so if file names
are longer, you will need more data).
