Looks like version 6.8.2 blows up the binary code size
significantly --- 3.9Mbytes vs 0.422Mbytes.
Is this a known issue with 6.8.2 ?
Is it a specific platform dependent issue --- i.e.
does it occur on linux machines ??
I can confirm HP's code size. I've no idea what went wrong (or
differently):
-bash-3.00$ ls -l hello
-rwxr-xr-x 1 maeder wimi 3907865 May 23 11:38 hello
That's platform dependent. It means on ghc 6.8.2 wasn't built with
split-objs enabled, so it includes a whole bunch of dead code normally
stripped out.
Consult whoever built the ghc on your platform, to ensure
they know how to build with split objects.

If the libraries were built with -fvia-C, we occasionally get
incompabitilities with newer versions of gcc and end up duplicating too
much stuff in the split .o files. If this is happening to you, please
report a bug.
Otherwise, please report a bug giving as much info as possible, and we'll
try to figure out what is wrong.
Cheers,
Simon
