Ogre segfault with std::_Rb_tree_insert_and_rebalance

Hello all.

I'm working on a 3d music visualizer using Ogre3d, basically it's a spectrum analizer, a lot like this old xmms plugin:
http://www.youtube.com/watch?v=_6NKBiwYN24
It works well, the bars are drawn and updated, there are no framerate issues, but it crashes randomly.
Sometimes it can run without problems, finish the song, other times it crashes instantly, other times the music just stops, without a crash.

Here is the source code for the main class : https://github.com/balazsbela/OgreVisua ... n.cpp#L221
