Comment(by marisn):

 On ~AMD64 Linux I don't see any crash but Valgrind is complaining about
 use of uninitialized values. Seems that there is a problem when vector is
 not a 3D one. Don't know it could be the source of a crash in the Windows
 version.

 Still in the light of recent Martin comments it could be the case.

 Markus - leak-check doesn't matter unless we are optimizing code. Lost
 memory is just wasted memory - it doesn't harm (except consuming few bytes
 of RAM).
