Ideally Austin would have, but fair enough.

That makes some sense, although IIRC the FPU is by default in double
precision mode as opposed to extended precision mode on Windows. (See
also signal_init_thread() in ntdll.) Does that also imply a similar
issue could happen if an application changed the FPU to single
precision mode?
