Comment (by strk):

 On my system both the values introduced in this patch return true from
 isnan():
 {{{
 #include <stdio.h>
 #include <stdint.h>
 #include <math.h>

 int main()
 {
   union {
     int64_t i;
     double d;
   } val;

   val.i = 0x7FF8000000000000;
   printf("%g is nan ? %d\n", val.d, isnan(val.d));

   val.i = 0x7FF7FFFFFFFFFFFF;
   printf("%g is nan ? %d\n", val.d, isnan(val.d));
 }
 }}}

 Could you run the same on your machine ?
 Chances are both are NaNs there too, in which case we're good to hard-code
 one version (could be quiet vs. signaling)
