When I try to use the "Align images" function in hugin-0.7.0-r1, it finds some control points and then proceeds with "Aligning images" when the progress bar almost reaches the end, hugin exits. Console log shows a segmentation fault. I tried not using the automatic aligning function, but performing some steps manually according to a tutorial on hugin website. A very similar error, resulting in hugin crash appears when I press "Optimise now" on the "Exposure" tab. Reproducible: Always Steps to Reproduce: 1. start hugin 2. load some images 3. press "Align images" Actual Results: Hugin crashes, console output indicates a segfault.

Created attachment 169438 [details] hugin console output console output. shows starting hugin, loading two images, pressing "Align images"
Created attachment 169444 [details] Manually selecting optimise exposure When I follow the tutorial at http://hugin.sourceforge.net/tutorials/two-photos/en.shtml hugin outputs this to console after pressing "Optimise now" in the "Exposure" tab. This might be another bug, but the sequence of events seems somewhat similar to the previous case.
What is your version of media-libs/libpano12 ? It is probably a libpano bug or version mismatch, because libpano version mismatch has caused optimization crashes in the past http://hugin.sourceforge.net/docs/manual/Hugin_FAQ.html
hugin-0.7.0-r1 ebuild depends on libpano13. Only available version is libpano13-2.9.12, which is installed. Seeing libpano13 depends on java - I have Sun JDK 1.6.0.07 installed.
Here is a basic gdb backtrace on the segfault after manually selecting exposure optimisation. Note I don't have -ggdb or any other debugging related CFLAGS on (I can recompile, if anyone would be interested) Iteration: 59, error: 8.630457: 40% Iteration: 60, error: 8.630455: 40% Iter: 60, estimate: 0.492972393 2.34888333 -0.203144065 0.208610242 -0.173616998 0.398680317 -1.37048287 0.996770563 12.2686456 -- errors 1.76012113e-05 0.359680326 Iteration: 61, error: 8.630455: 40% Program received signal SIGSEGV, Segmentation fault.

As I am unable to reproduce this, I filed a bug report at the hugin project page (see the URL field).
Today I tried compiling hugin directly from the tarball - it worked. I went to test if any of my CFLAGS might be the problem. Suddenly, I can't reproduce the bug either - hugin magically started working after an emerge a now seems to work without problems. I'm not aware of making any significant changes to the system. Only: - Did an emerge -DNu world this morning to get updates since my last post, but nothing seemed to be anyhow related to hugin. - Installed LAPACK and some other numerical libraries. Coincidentally, I have noticed, that hugin might be able to use them - near 28% of copmilation, it issues a warning about missing LAPACK, even if I have several implementations installed and working, this might be related to the problem (altough I doubt it)
Just thought I'd say 'me too', also have this problem on on unstable amd64, with an identical backtrace. I'm going to recompile hugin, see if it makes a difference. I am using libpano13-2.9.12 and the icedtea OpenJDK.
closing, as this doesn't seem like a hugin bug.
