Great that was it.  I have been using -O2 as this is considered safe and I 
perfer my system to be stable (therefore I am not using -O3).  This is the 
first thing I have encountered that had a problem this this optimization 
flag. 

I also created an ebuild for libpano12-2.7.0.9 which is the newest version on 
sourceforge.  It says in the change log that some changes were made for 
amd64.  So I figured this was worth a try.  But it was also giving me seg 
faults like 2.7.0.8.  Removing optimization fixed the problem so now I have 
everything other than PTStitcher working on my amd64 machine in 64 bit mode.

I downloaded and installed the Windows versions of this stuff just to see how 
it compared.  I have to say that it was not nearly as "stable" as running it 
in Linux.  Not that the Linux version is super stable but for every one thing 
that causes Hugin (and other related tools) to crash on Linux there must be 
five ways to get the Windows version to crash.  The only real advantage was 
being able to run PTStitcher.  

In spite of how unstable the Windows version was I was able to get a very nice 
stitch of a photo of the Hughes H1 replica that I shot at the air races in 
Reno.  I could not get back far enough to get the whole plane in a single 
frame even with a very wide lens so I hand held two shots.  Used PTStitcher 
to do the stitch.

At this point I am fairly pleased with how this is working on my Linux box.  
There are a few things that will cause it to crash but for the most part it 
is stable and I have everything needed for a complete workflow.
