Bug Description

System: fedora f22 x86_64
hugin 2015.0.0 rc1 c48252eb571f
libtiff-4.0.3
libpng-1.6.16
libjpeg-turbo-1.4.0
vigra-1.10.0

I'm getting a segfault from nona with PNG and TIFF output, JPEG is fine.

This is a simple single image project with JPEG input:

nona -i 0 -m TIFF -o junk project.pto
Segmentation fault (core dumped)

Result is the same with or without -m parameter and with multiple photo projects.
OMP_NUM_THREADS=1 doesn't help. I don't have a suitable GPU so I can't test that.

I can't reproduce the issue. It works for be.
Nevertheless I have an idea. Please test if changeset 5f45958ae420 fixes your issue. If so we need to graft the changeset to 2015.0 branch.

Thanks, that works.

The current 2015.0 branch (dc7eb38fe1d5) patched with 5f45958ae420 now renders TIFF without crashing.

(this is a 2015.0 bug. 2014.0 is fine, I even rebuilt it to be sure there is no problem with the build environment. All this is with the same vigra impex 1.10.0 library)

Ok, grafted to 2015.0 branch.

2014.0 is using an internal vigra (very old version). So you did not see the bug. Pablos old implementation does not work with the newer vigra version. So Hugin is now using slightly modified impexalpha.hxx from vigra directly (written by Chris Spiel).

Hi Bruno,

during testing I found some more bugs in the alpha channel handling, which only occurs in some special cases. Nevertheless I tried to fix them. This requires a touch up of some more code in changeset 13f7aeff8000
Could you please test that I did not break something what already worked?
