Summary: Segfault when using clock expressions in liveness properties

Description Ferdy Hanssen 2005-07-13 17:08:34 CEST
When you verify the accompanying query on the accompanying model (I have trimmed
the model and query a lot from my original, and this one still segfaults).

If I change the value of mx_lost in the model from 1 to 0 the segfault does not
occur.  If I remove the bit "and rec_time == 0" from the query, the segfault
also does not occur.

A fix has been committed to CVS (it was a missing exclamation mark). 

The problem is triggered by expressions over clocks in liveness or leadsto properties.
