The inention is that archive classes be interchangeable. So if a
fails for one archive class and not for another, it would be a bug by

As of now, there the only known instances of this occuring is with the
serialization of Nan floating point numbers which fails on text/xml archives
but passes with native binary archives.

Which is kind of interesting since both of these archive classes use
the same i/o implementation. So it must be in text_?oarchive which
after all isn't very big.

I do sympathize and much appreciate the effort you have to expend
to narrow this down. It hasn't been reported so it must be pretty
obscure. Sorry, I can't be of more help.

BTW, the best thing for me in these cases is to run under the debugger,
trap when fault throws, and inspect the call stack (which is going to be
long). So maybe it won't be so hard to track down once you can
reproduce it.
