I could not reproduce the error with the steps had been specified.

* archived config file didn't compile Visconti VIIF driver (at least, COMPILE_TEST is needed)
* the error message didn't appear even if I add some options to config file.
* Environment:
  * OS: Ubuntu 22.04
  * compiler: Ubuntu clang version 15.07

Yuji Ishikawa
