No, the function is executed on both archs. I agree that it doesn't
relate directly to x86_64.
Though Olivier confirmed the problem isn't present on x86 with a USB
partitioned disk, the boot partition at the end of the disk, whereas
it crashes with a page fault on x86_64.
A reason could be that the partialBuffer pointer could point to a
valid mapped memory in 32 bits, whereas on 64 bits it doesn't. Just a
guess.
Bye,
Jérôme
