I don't think anyone really has a plan :)  However it seems wrong that the
compiler should either crash (if built with checking enabled) or produce
wrong code (if built with checking disabled) when passed -m96bit-long-double,
so please open a bug report anyway.  Probably the implementation would be to
generate [12 x i8] for long double memory when passed the flag.

Ciao,

Duncan.
