--- Comment #1 from Martin Storsjö  ---
I primarily debugged this on arm, but it does seem like the same modification
(forcing loading modules at an address different from the default image base)
breaks things on x86 too.

In this case, it seems like perform_relocations() gets an address different
from where it actually ends up mapped. On x86_64, perform_relocations() gets
both module and nt->OptionalHeader.ImageBase equal to the original image base
address, while on ARM they end up with an entirely different address (not the
original image base, nor the address where it actually ended up mapped).
