Compiler broken?

The following quaternion code that used to compile perfectly now crashes:

- (id)initAsProductOf:(Quaternion*)q1 mult:(Quaternion*)q2
{// It breaks here with error: "Internal compiler error: Segmentation fault"
if (self = [super init])
{
double* q1El = q1.elements;
double* q2El = q2.elements;


elements[3] = q1El[3]*q2El[3] - q1El[0]*q2El[0] - q1El[1]*q2El[1] - q1El[2]*q2El[2];
elements[0] = q1El[3]*q2El[0] + q1El[0]*q2El[3] + q1El[1]*q2El[2] - q1El[2]*q2El[1];
elements[1] = q1El[3]*q2El[1] + q1El[1]*q2El[3] + q1El[2]*q2El[0] - q1El[0]*q2El[2];
elements[2] = q1El[3]*q2El[2] + q1El[2]*q2El[3] + q1El[0]*q2El[1] - q1El[1]*q2El[0];
}
return self;
}

Can anyone spot an obvious mistake made by me, and if not, has anyone else run into these problems?
It breaks with the system default compiler, GCC 4.2. However, it works perfectly with LLVM-GCC 4.2.
