assert()ion hit during training

[GoogleCodeExporter]

While training a QRF model, rf-ace dies with this assertion:

rf-ace: src/node.cpp:483: bool Node::regularSplitterSeek(TreeData*, size_t, 
const ForestOptions*, distributions::Random*, const std::vector<long unsigned 
int, std::allocator<long unsigned int> >&, size_t&, std::vector<Node, 
std::allocator<Node> >&, Node::SplitCac
he&): Assertion `splitCache.newSplitFeatureIdx != targetIdx' failed.

This happens with version rf-ace 1.2.5. The previous version (1.1.0) worked 
fine with the same configuration and the same training set.

This is on Debian Lenny / amd64, using the command-line tool.
