If you run and build a debug version of ipc_perftests, such as with this gn settings:

is_component_build = false
is_debug = true

then ipc_perftests will fail with this message:

    c:\src\chromium4\src\ipc\ipc_perftest_support.cc(289): error: Value of: WaitForClientShutdown()
      Actual: false
    Expected: true

The full output is:

> ninja -C out\debug ipc_perftests & out\debug\ipc_perftests --gtest_filter=MojoChannelPerfTest.ChannelPingPong
ninja: Entering directory `out\debug'
ninja: no work to do.
