after a bit of actual thought, i think that NaN
is supposed to generate a note.  if you do catch
the note, the program should work fine.

e.g.

#include <u.h>
#include <libc.h>

void
note(void *, char *s)
{
	if(strncmp(s, "sys: fp: ", 8) == 0)
		noted(NCONT);
	noted(NDFLT);
}

void
main(void)
{
	double d;

	notify(note);
	d = NaN();
	print("%g\n", d);
}
