This is with OSX 10.4.9 on a PowerMac Quad G5, 4.5GB RAM.
Xcode here is version 2.3, gcc 4.0 (upgrading to Xcode 2.4.1 now,
though a friend was able to confirm the bug with 2.4.1 on an Intel
mac). I figured it would be easy enough for you to copy and paste the
code and try it out in your configuration... (or does it not crash
there?) The crash occurs here regardless of target platform, so the
bug must be in the preprocessor somewhere. Anyway, is this the
preferred syntax for initializing an array of vectors, or is there a
better way?
Thanks
Ben

The following function kills gcc on my G5 with Xcode. Can anyone
else repeat this? Bizarrely, when the array is extended to 5
elements, or when I use 'vector float' instead of the typedef, it
compiles fine....
It's easier to provide assistance if we know what environment you
are working with (OS version, Xcode version, gcc version, ...).

static void foo() {
#if __VEC__
typedef vector float vfloat;
#elif __SSE__
typedef vFloat vfloat;
#endif
vfloat mult_[4] = { { 1.0f, 1.0f, 1.0f, 1.0f },
{ 2.0f, 2.0f, 2.0f, 2.0f },
{ 3.0f, 3.0f, 3.0f, 3.0f },
{ 4.0f, 4.0f, 4.0f, 4.0f } };
}
