Can't be trivially fixed - error is a symptom of deep internal type confusion between handle (gzFile), pointer to handle and a pointer to a pointer to handle. This depth of indirection does not appear required. Trivially changing all error sites to take address of passed parameter and get double-pointer that way most likely will break this program, as it checks if returned handles are non-null. I am unwilling to put an effort to fix this program all the way, it would require rewriting a lot of it.
