# Bug#35242734: Signal 11 due to missing UDF file
#
# Test that server correctly handles the call to invalid
# UDF function, even after the server was restarted.
#
# Server restart code is based on main.restart_server test
# (using RESTART command with server started by supervisor process)
# because restarting through standard MTR mechanisms reinitializes the
# mysql.func table content (and this test needs the content
# to be preserved after restart).
#
# Hangs forever with ASAN and gcc >= 10.0
