That was not quite correct. Parallel mark indeed does not seem to work 
here. Or is it depending on the weather ...

Ok, I think I found a reason. The gctest does not use GC_INIT anymore 
for this target. Adding a GC_INIT again makes my G4 under Leopard (aka. 
10.5.1) work with and without parallel-mark. Yes, with and without, 
double checked.

But as said, Tiger on G4 was ok w/o modifying test.c.
