This part of the hunk is fine: if ULONG_MAX is not 2^32-1, then 2^33-1 will fit in a long. > +#if TIME_MAX == 0xFFFFFFFF > +#define USTAR_MAX_MTIME TIME_MAX > +#else > #define USTAR_MAX_MTIME 077777777777UL > #endif But this is not: just because TIME_MAX is not 32 bits, does not mean that long is also more than 32 bits. We need this: diff --git a/archive-tar.c b/archive-tar.c index aadd5865f6..b5d6ce27d3 100644 --- a/archive-tar.c +++ b/archive-tar.c @@ -33,7 +33,7 @@ static int write_tar_filter_archive(const struct archiver *ar, #if TIME_MAX == 0xFFFFFFFF #define USTAR_MAX_MTIME TIME_MAX #else -#define USTAR_MAX_MTIME 077777777777UL +#define USTAR_MAX_MTIME 077777777777ULL #endif /* writes out the whole block, but only if it is full */
