Hello,

I found something that I believe to be a bug in the serialization of
double: in byterun/extern.c the "caml_serialize_float_8" function just
calls the "caml_serialize_block_8" function to serialize its float while
in intern.c the "caml_deserialize_float_8" function calls the
"caml_deserialize_block_float_8" function which performs more work than
the "caml_deserialize_block_8" function.

And indeed, I had trouble serializing custom values with
*serialize_float_8 functions, until I replace these calls either by
their *_block_8 or the *_block_float_8 equivalents (I suppose that the
later is better).

Should I fill a bug report for this? or is there something I do not know
about the use of these functions?

Thanks.
Mathias
