We're seeing the following ICE, both with gcc 4.1 and latest 4.2 (but 4.0
works). Apparently it only happens on x86_64. It works when you drop the
optimization flag.

It works in 4.2.0 for sure. It does fail in "4.1.2 20060608" though.

Here is a C testcase (so that it does not get marked as P5):
typedef struct _NSPoint NSPoint;
struct _NSPoint
{
float x;
float y;
};
static inline NSPoint
NSMakePoint (float x, float y)
{
NSPoint point;
point.x = x;
point.y = y;
return point;
}
static inline NSPoint
RelativePoint (NSPoint point, NSPoint refPoint)
{
return NSMakePoint (refPoint.x + point.x, refPoint.y + point.y);
}
NSPoint g(NSPoint refPoint)
{
float pointA, pointB;
return RelativePoint (NSMakePoint (0, pointA), refPoint);
}

I don't think that's correct. I can confirm that gcc 4.2 20060508 works, but
20060530 and 20060613 definitely fail here (both the C and Objective-C test
cases).
