Hi,
I'm not sure if rust even officially supports this (maybe should open an unsafe-guideline discussion?)
but basically you can initialize arrays by linking into the right place in elf/exe etc but miri doesn't run this

FWIW c2rust uses this to initialize global statics.

I think this is a duplicate of #450 ?
