ngrest crashes upon CTRL + C #83

Hi Dmitry,

I made some recent changes to bring up the ngrest server using two shared libraries/objects (It was originally one, I modularized them into two libraries). When I exit the ngrest server (ctrl + c), it crashes every time with the following message. Do you have any suggestions for troubleshooting this.

Try attaching to the ngrest process with gdb. press Ctrl+C in ngrest and examine stack in gdb

Also Valgrind is the good tool to find memory errors. If you use QtCreator, it's easy to access it from Debug menu : Change "Debugger" to "Memcheck"

Thank you Dmitry, I too had a similar debugging thought process to try this, but posted the question if any similar issues was seen in the past as well. Will try this.
