spin compiler hangs on complex ltl expression

When doing 'spin -a p3c.pml' on the following (not so useful) program, the spin compiler seems to hang.


bool p;
bool q;
bool z;

ltl p3c {p V q V z W q W q W z}

init{skip;}

Re: spin compiler hangs on complex ltl expression

this one is just an issue of complexity.
the tool just churns on this forever, because it expands so much
simplifying the formula (or shortening it) will help
