[support/minizip/unzip.c:733]: (error) Uninitialized variable: file_info_internal

I don't know how to fix it

This is a false positive from your static analyser.

Following the code:

unzlocal_getLong does assign either zero or the decoded value to the supplied pointer.

unzlocal_GetCurrentFileInfoInternal pass &file_info_internal.offset_curfile to unzlocal_getLong.

file_info_internal is of type unz_file_info_internal, which is just a single long, so the store in unzlocal_getLong will fully initialize the struct.

sorry i missed this line while rereading

cppcheck give a lot of false positive :(
Comment 3 Rodrigo Kumpera 2014-02-13 09:41:33 UTC
It found a real bug in marshal.c and that's what count. :)

Thanks for going through all those reports.
