  Log Message:
  -----------
  fuzz_scconf_parse_string: Limit maximum size of input data

Too long input is not necessary for parser testing.
Huge test cases containing mostly opening brackets caused
stack-overflow while freeing the memory of chained blocks.
Test case containing a too-long list of values caused
timeout.
