>Description:
	Assigning HUGE_VAL from /usr/include/math.h to a variable of type
double causes an unaligned access error/warning.
>How-To-Repeat:

% cat testing.c
#include <math.h>

int main(void)
{
  double d = HUGE_VAL;
  return 0;
}

% ./testing
pid 848 (testing): unaligned access: va=0x1602aa16c pc=0x120000afc ra=0x120000760 op=ldt
>Fix:
	Don't know, but all that casting around certainly looks problematic
to me :)

extern const char __infinity[];
#define HUGE_VAL        (*(const double *)(const void *)__infinity)
