What steps will reproduce the problem?
1. Compile sources
2. Run included test
What is the expected output? What do you see instead?
The test will crash.
What version of the product are you using? On what operating system?
cpp-btree 1.0.1 on MacOS X 10.7.5 , i686-apple-darwin11-llvm-g++-4.2
Please provide any additional information below.
Similar crash will happen if I load with some values and call clear method or
assign empty btree to full btree.
