Dear Maintainer,

when I run dcraw with following parameters on a known good dng image,
it produces black image on aarch64 and fails with 'Floating point
exception' on amd64.

dcraw +M -H 4 -o 1 -q 3 -T -fbdd 1 1.dng

when I use dcraw_emu from libraw-bin package with exactly the same
arguments, produced image isn't black.
