Re: floating point library problems ...

Could you have some kind of problem with the endianness of doubles? See
if you get the same problem with floats and work from there.

At least on ARM, gcc assumes doubles are big-endian (the words are in
the opposite order to the one you would expect, but within a word they
are little endian). These leads to some weird results for the unwary...
