Runtime error: SIGSEGV and SIGABRT

[jinxy17]

@xqgex Thanks for the code & comments! A great complement to the original paper.
However my server can compile the program but always encounter either SIGSEGV or SIGABRT. Any possible fixes to that?

Best,
X.J.

Hi X.J,
Unfortunately the original paper is missing important parts, I did my best to try to implement it, and posted it publicly in the hope that someone could continue my efforts.
