+    Call get_config_max() indirectly through
+    rtems_configuration_get_maximum_semaphores() with a specially manipulated
+    argument to enter an if-branch only accessed when unlimited objects
+    are configured.

+    uint32_t max = rtems_configuration_get_maximum_semaphores();
+  checks:
+  - brief: |
+      The value returned by the function call must be the one artificially
+      injected by this test.

+      T_eq_u32( max, SEMAPHORES_PER_BLOCK | RTEMS_UNLIMITED_OBJECTS );

+  Parts of the file ``cpukit/sapi/src/getconfigmax.c``
+  are only executed when unlimited objects are configured.  The
+  space qualified code subset does not support this feature.  This test
+  exercises the code parts otherwise not reached in order to achieve full
+  code coverage.
