You deliberately use a very large storage for a very little data.
And it fails on m64 and not m32 which is rather weird and odd.
So I went to the bottom of this number which appears to be 3920.
3920 = ok
Any number beyond 3920 fails on m64 wtf?
I have no idea what is going on.
It just seems to me interesting to test out your case...
Yes O0 fails also... who knows...
