#
# This test suffers from server
# Bug#38124 "general_log_file" variable silently unset when using expression
# In short:
#    SET GLOBAL general_log_file = @<whatever>
#    SET GLOBAL slow_query_log = @<whatever>
# cause that the value of these server system variables is set to default
# instead of the assigned values. There comes no error message or warning.
# If this bug is fixed please
# 1. try this test with "let $fixed_bug38124 = 0;"
# 2. remove all workarounds if 1. was successful.
