False positive on zlib defalte usage?

The zlib example code (demonstrated in http://zlib.net/zlib_how.html and available from http://zlib.net/zpipe.c) is reported as "Uninitialized variable: out" on line 70. The out buffer is indeed unitialized, but passed as strm.next_out to deflate function where it is used. I'd consider this as an edge case. What is best practice here? I know I can silence the error diagnostic via // cppcheck-suppress uninitvar comment.

Seems I can't edit the topic typo defalte->deflate.

The code looks similar to this issue: https://trac.cppcheck.net/ticket/12461

Right, pretty likely a duplicate. Thanks for the pointer.
