Ouch. So i managed to *crash* the microsoft compiler with my code?
Could you please somehow have a look if this is reproducible? If it's
reproducible or hard-to-check-if-reproducible then i'd revert.
I don't think i can debug this, as i don't have windows, and i have no
guesses from looking at the code.
Also, should i have received an email for this failure? Cause i haven't
received an email for this failure. Hope there aren't more failures.
