 Adding the full gdb backtrace for reference:

 The problem is that y = NULL. The test in tavl.c:139 should have been
 positive (new empty tree, the root must be set to the new node).

 With regard to lib/vector/dglib, the source code of the Debian package
 seems to be identical to svn source code. Therefore, as long as manual
 compilation from source works, it seems that this is a packaging error.
 FWIW, I have updated tavl.c in trunk r69935 (newer version, more safety
 checks).

 For debugging purposes, is there any way to reproduce compilation of the
 Debian package? It would be really nice to have a working Debian package.
 Increasing priority.
