hugin (Win32) crashes only when masks involved

[tbransco]

Trying to align and enfuse a single, handheld 3-image EV bracket, but Hugin crashes if I add Exclude or Include masks. I have tried this with OOC JPEGs and two types of 16-bit TIFFs (created by RawTherapee 4 and Olympus Viewer 3), but the result is the same. I've attached my PTO file for when I do NOT add a mask and everything works as expected. If the PTO of the failed version is required, please let me know.

Steps I take:
1. Add images
2. Interface=Advanced
3. Deselect all images and set stack size = 3
4. For images 2 and 3, set Lens to 'New Lens'
5. Unlink and deselect all images
6. Use 'Align image stack' to find CPs
7. Remove CPs from clouds in first pair of images (0 EV and -1.7 EV) using Control Points tab (no CPs in clouds for +1.7 EV)
8. Deselect images in Images tab, and 'Clean control points'
9. Add one or more Include masks (when Exclude type was default, Hugin crashed as soon as I changed the mask type to Include)
9. On Images tab, optimize on Positions Only
10. On Images tab, optimize on Positions, View, and Barrel <-- CRASHES HERE when I click 'Calculate' button
