Note: BHI produces a conjunction of expressions, but the retrieval
mechanism currently retrieves the expressions after they have been
broken up, and so only the last one survives. The correct expected
value for this test is:
((gv_0x4d95_in <= 145) and (gv_0x4d95_in >= 0))
but we only see the last one being reported.

At some point this should be fixed.
