The meaningful part is just outside of this hunk:

  gdb_test "info record" [multi_line \
    "Active record target: .*" \
    "Recorded 19 instructions in .+ functions \\(. gaps\\) for thread 1 \\(Thread .*\\)."
  ]

We check that we actually stepped exactly those 19 instructions.  The test doesn't
care where this brought us.

Markus.
