+# ==== Purpose ====
+#
+# Test verifies that "init_connect" and "init_slave" system variables work
+# fine when "profiling=on".
+#
+# ==== Implementation ====
+#
+# Steps:
+#    0 - Create regular user without super privilege so that "init_connect"
+#        variable is effective.
+#    1 - Enable profiling.
+#    2 - Start a new connection which will try to execute the statements
+#        specified in "init_connect". No assert should be reported.
+#    3 - Execute SHOW PROFILES to verify that statements specified in
+#        "init_connect" are displayed as part of profiling.
+#
+# ==== References ====
+#
+# MDEV-22706: Assertion `!current' failed in PROFILING::start_new_query
