Newbie here, trying out Zorro. I started working my way through the workshops, but when I try to run workshop4.c it reports "Error 111: Crash in run: run() at bar 1190" (see screenshot attached). Same for workshop5.c

Documentation for error 111 suggests division by zero, stack overflow, array index out of bounds, etc. Since I am just running an unmodified example script, I assume that is not the case here.

System:
Zorro 2.50.2
Windows 10 (running in VirtualBox on Mac)
8 GB RAM
4 cores (Intel i7)

Please advice
