using more than one physical processor, which is unacceptable because
the application is intended to be multithreaded. The problem seems to
be more consistent when application is allocating more memory (eg.
more trees >10000), sometimes everything works fine if the memory
allocation is not so demanding.

+This are the latest test I performed with some more descriptive
+debugging information. As I stated before the error is constant with
+memory comsumption. On SMP Linux system with 1GB of RAM it took 20000
+trees to produce an error, while on SMP Linux system with 2GB of RAM
+it took 40000 trees.
+
+Hope this helps a bit. Cheers!
