It looks like gcc 4.1 is floating all the

     __asm__("\n__stg_split_marker:");

results to the top of the file, so the splitter sees only a number of
empty sections followed by one large one. Results of

    echo 'module Foo where' > Foo.hs
    for i in `seq 1 10`; do echo "foo$i = 'c'" >> Foo.hs; done
    mkdir Foo_split
    ghc -O -split-objs -c Foo.hs -v -keep-tmp-files

are attached, using

    $ gcc -v
    Using built-in specs.

Amd64 doesn't seem to be afflicted.
