Good, i suppose.

Debug build will not help.

Please try adding 2 following lines:
fprintf(stderr, "%s roi in %d %d %d %d\n", self->name(), roi_in->x,
roi_in->y, roi_in->width, roi_in->height);
fprintf(stderr, "%s roi out %d %d %d %d\n", self->name(), roi_out->x,
roi_out->y, roi_out->width, roi_out->height);

For 2.0.x, here:
https://github.com/darktable-org/darktable/blob/darktable-2.0.x/src/iop/denoiseprofile.c#L1384

And for master, here
https://github.com/darktable-org/darktable/blob/master/src/iop/denoiseprofile.c#L1789
AND here 
https://github.com/darktable-org/darktable/blob/master/src/iop/denoiseprofile.c#L1800

And repeat that -d perf, zoom to 1:1 and move around.
