Public bug reported:

I have 23 images in the list which I am aligning with hugin. I made a
mask on the first image, and set it to "exclude region from all images
of this lens".

I made CPs, and they were excluded from the mask (thanks for the recent
fix).

Then I stitched (generating remapped images, no exposure correction, low
DR), but I forgot the mask was there, and so the region was not present
in the images -- this seems correct (not a bug).

So I changed the mask type to "include region" and ran the stitcher
again.

The first image was normal: the whole image was generated. The other 22
images, however, lacked the region, as if they all had the same mask but
it said "exclude". I'm not sure if this is a bug, but it surprised me:
with just one mask, on one image, set to "include", it excluded that
region from all the other images. Maybe it's normal -- just reporting it
in case.

Second issue:

So I removed the mask entirely -- now there were no masks at all on any
image. I ran the stitcher again, and the result is obviously a bug: many
images with strange, random masks, as if the masking data is corrupted.
A few examples are attached. I note that between running the stitches I
was recalculating the geometric optimizations.

This is with hugin via the nightlies ppa, commit b55e2c48db83, on
Kubuntu 16.10.
