It seems that the optimizer keeps array assignments live when passing
the array as a pointer, but not when passing the address of an element.
Found when testing the following code:
BasisBlade *pga_blades[16] = {
blades[1], blades[2], blades[3], blades[4],
blades[7], blades[6], blades[5], blades[0],
blades[8], blades[9], blades[10], blades[15],
blades[14], blades[13], blades[12], blades[11],
};
BasisGroup *pga_groups[4] = {
[BasisGroup new:4 basis:&pga_blades[ 0]],
[BasisGroup new:4 basis:&pga_blades[ 4]],
[BasisGroup new:4 basis:&pga_blades[ 8]],
[BasisGroup new:4 basis:&pga_blades[12]],
};
Only the first element of pga_blades is being assigned in the optimized
code, but everything is correct when not optimizing.
