Wanna know something funny?
Having a printf fixed the segfault. Without it, it would crash.
So the workaround in read_kickstart (memory.cpp) was to add
"volatile int i" instead of "int i".

Just one simple printf("Value of i: %d\n", i); was enough to not segfault.

That's probably not the real fix, unless you have another thread accessing
i.


Hm.. perhaps.
Is there a way to see how the code looks like with different optimization flags?
