Postcondition Trap77 when running the basic example from documentation

[WildPenquin]

Hi,

I can not get this to work currently. The very basic example crashes with an error when running MultiBUGS with TRAP 77 (postcondition violated).

This is on Linux and I'm using the multibugs binary from https://www.multibugs.org/

TRAP 77  (postcondition violated)
