Hmm...  Looks like a unified diff to me...

|unzoo.c: In function 'IsMatchName':
|unzoo.c:1268:40: error: array subscript has type 'char' [-Werror=char-subscripts]
|         else if ( *pat=='?' && ! IsSpec[*str] ) { pat++;       str++;       }
|                                        ^
|unzoo.c:1271:40: error: array subscript has type 'char' [-Werror=char-subscripts]
|         else if ( tmp != 0  && ! IsSpec[*tmp] ) { pat =   pos; str = ++tmp; }
|                                        ^
|
|This looks indeed like undefined behavior since the function IsMatchName
|accepts arbitrary filenames, and filenames containing non-ASCII
|characters would access the array outside of its bounds.
|
|On NetBSD-8.0-x86_64 using GCC 5.5.0 the memory below IsSpec is BufArch,
|which means that pattern matching depended on the contents of the archive
|before.
