# Make sure False has one acceptance set when generating Büchi automata
test 1 -eq `../../bin/ltl2tgba -B false --stats %a`
# In particular, Spot 0.9 would incorrectly reject the sequence:
# (a̅b;a̅b;a̅b̅);(a̅b;a̅b;a̅b̅);(a̅b;a̅b;a̅b̅);... in 'G!{(b;1)*;a}'
# This means the following automaton was incorrectly empty in Spot 0.9.
