Unable to launch the 2D cuckoo hashing example

[mxdwudongyu]

The -DABY_BUILD_EXE=On option seems to have successfully built the executives for all the examples. I tested them and all ran fine except for the psi_2D_CH_test one. The command I gave: ./psi_2D_CH_test -r 0 -n 32 -b 16 -q 0 The response gives: Cardinality threshold: 0 Segmentation fault (core dumped) The debugger says the function free() was mistakenly used. After some checks I discover nothing wrong. I also noticed that the pointers in the 2D hashing as well as the 2D circuit cpp file went one level higher (say, from double to triple). I doubt that would be the problem.
