If you really have no issues on 32-bit OS you can try to analyze the experiment there. Copy the experiment (exp) and needed (exp/all/*.so) binaries (for example only this one to understand whether it helps). Try to convert it: vtdpview exp -c.
If you still have problems try: disasmtool <binary>.
In case it also crashes and the binary is not anyone's secret share it with us.
In case disasmtool does not crash then share with us the experiment directory and problematic binary.
It is always encouraged to mimize the amount of provided data.
