1) take blank model with just Template 2) add a parameter to Template "int ¶m" 3) add an edge loop 4) goto System declarations, 5) remove Process instantiation 6) replace Process with Template 7) press F7, everything is fine 8) save the system, say bug.xml 9) goto verifier, say "A[] not deadlock" and save the query, say bug.q now you can try either, simulator or verifier and they will give OutOfMemory exception. Expected result: should complain about uniniatialized parameter and prevent from simulation/verification.
