I am terribly sorry for the bad formatting, I only got aware of it after 
sending the mail. Won't happen again :)

How can I check for proper stack-alignment? (I am terribly bad at 
assembly, so should any asm be required a code-snippet would be great).
I tried compiling using using "-mpreferred-stack-boundary=4" and using 
the aligned-attribute when defining the Vector3D-class, but neither did 
solve the problem.

I know, but unfortunately I was not able to write a small testcase that 
reproduced the problem (that's the point I was trying to make when 
posting that last snippet), I'm working on it, though. :)
