# Bug#9112 - Merge table with composite index producing invalid results with some queries
# This test case will fail only without the bugfix and some
# non-deterministic circumstances. It depends on properly initialized
# "un-initialized" memory. At the time it happens with a standard
# non-debug build. But there is no guarantee that this will be always so.
