This works for me in editmode and object mode with all nurbs/surface types.

also tested with valgrind and with floating point exceptions enabled, with no results.

OSX 10.5, PPC, goes fine for adding Nurbs donuts and spheres, with align to view.

Anyway, for any good bug report here you have to ensure that other people can redo an error. Always at least mention if you have tested the official release:
http://download.blender.org/release/Blender2.56beta/

And check if things go fine with previous version (2.55 release), and if this happens on other systems for you too.
Then test it with 'factory settings' too (file menu), and/or save us a .blend file that gives you a crash immediate on adding objects aligned to view.

Hi Guys,

Tested also with official release, Blender 2.56beta, with same crash. Factory settings do not produce. Once changing the default align to "world" and changing to "view" in the User Preferences induces crash. At least here oddly.

Please see the following:

Video of the crash: http://screencast.com/t/wQGxGfIJDh3J
Report of official: http://home.ptd.net/~kslifer/NurbsCrasher/NurbsCrasher1.txt
Report of svn: http://home.ptd.net/~kslifer/NurbsCrasher/NurbsCrasher2.txt
Sample of official: http://home.ptd.net/~kslifer/NurbsCrasher/NurbsCrasherSamp.jpg
Profile of official: http://home.ptd.net/~kslifer/NurbsCrasher/NurbsCrasherProfile.jpg
Malloc trace: http://home.ptd.net/~kslifer/NurbsCrasher/NurbsCrasherMalloc.jpg

Not sure any of that is of use. The .jpg files show some of the last events recorded. Something I'm noticing though, is the difference in the two crash reports with the line "surf_prim_add + 18" in the official beta version report. This line doesn't show up in my svn version report, and it was svn version that first created the application preference file. Let me putz with that and I'll report if that changed anything.

Ahh yeah, and a .blend file if that helps:

Just tested in Blender 2.55beta and the same procedure will crash blender.

I also removed all the stored preference files located in ~/Library/Application Support. I still get the crash from original posted procedure. Perhaps you are using the side bar to align to view? This seems to work fine. You need to try setting this in the User Settings/Preferences for it to crash.

You will see, new objects align to "view", set in User Preferences, rarely works on any objects, mesh, etc. Though it seems to only crash when on nurbs spheres and donuts. Perhaps that could be another clue as to what is happening here?

I knew it, we need better language to describe things in Blender. :)

You are using the top menu bar "Add", which is not in 3d window context, so it cannot add view aligned.
I assumed everyone was using the shift+A shortcut...

Anyway, curve code had bad checks for active 3d window there, that's fixed in svn now. It doesn't crash, but view-aligning doesnt work either via menu.
