# The fix for ticket ec32177c99ccac2b180fd3ea2083 only makes a difference
# in the output when there is a TERM_VNULL entry in the WhereClause array.
# And TERM_VNULL entries are only generated when compiling with
# SQLITE_ENABLE_STAT4. Nevertheless, it is correct that TERM_VIRTUAL terms
# should not participate in the factoring optimization. In all cases other
# than TERM_VNULL, participation is harmless, but it does consume a few
# extra CPU cycles.
#
# The following test verifies that the TERM_VIRTUAL terms resulting from
# a GLOB operator do not appear anywhere in the generated code. This
# confirms that the problem is fixed, even on builds that omit STAT4.
