Indeed that resolves the issues I encountered in the trunk code.

well I did ignore the following compilation warning:

boost-trunk/boost/interprocess/containers/container/detail/tree.hpp:328:31: 
warning: returning reference to temporary

which does not occur when using the correct "const key" allocator.

anyways, thank you very much for your help,
