------- Comment #4 from ubizjak at gmail dot com  2009-08-01 22:04 -------
Confirmed as gcc-4.5 regression.

Reduced testcase:

--cut here--
extern struct
{
  int demoplayback;

  float movetype;
  int cameramode;

  float idealpitch;
  float pitchvel;
  int nodrift;
  int paused;
  int onground;
} cl;

void V_DriftRoll (void);

static void
V_DriftPitch (void)
{
  float move;

  if (!cl.onground || cl.movetype == 5 || cl.movetype == 8
       || cl.demoplayback || cl.nodrift )
    return;

  move = cl.pitchvel;

  if (cl.idealpitch > 0)
    ;
  else if (cl.idealpitch < 0)
    {
      if (move > -cl.idealpitch)
          cl.pitchvel = 0;
    }
}


V_RenderView (void)
{
  if (!cl.paused  && !cl.cameramode)
    {
      V_DriftPitch ();
      V_DriftRoll ();
    }
} 
--cut here--

gcc -m32 -march=i586 -ffast-math -O2:

test.c: In function ‘V_RenderView’:
test.c:45:1: internal compiler error: in get_hard_regnum, at reg-stack.c:741
Please submit a full bug report,
