Skylark core dump

Hi,

When you start Skylark with prefork = 1 and then press CTRL+C, Skylark will create a core dump.

Steps to reproduce:

1. Open Skylark09 example
2. In the file main.cpp change prefork = 0; to prefork = 1;
3. Build the Debug version of Skylark09
4. Open shell, change directory to the Skylark09 build output directory and execute the binary
5. Press Ctrl+C => core dump is created

Ubuntu 20.04, gcc 9.4.0 or clang 13.0.1
