This occur when using "or", "exists" and "extends"
A minimal test case is available on github
In this test case :
if we comment line number 35 , any error are raised
if we uncomment line number 10 , any error are raised
if we remove all "exists" words, any error are raised
If the same rule is write using named consequence the test pass.
