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.
