I found two: powerpc-apple-darwin8.11.0 --- out 2008-10-25 +++ exp 2008-10-25 @@ -1,2 +1,2 @@ -18446744073709551615 +9223372036854775807 9223372036854775808 FreeBSD i386-unknown-freebsd6.1 + diff -u out exp --- out 2008-10-25 +++ exp 2008-10-25 @@ -1,1026 +1,2 @@ 9223372036854775807 9223372036854775808 -9223372036854775808 -9223372036854775808 ... -9223372036854775808 -9223372036854775808 While neither is new and both should be addressed, fixing corner cases like these is not high priority for me. Obviously, using gmp here (like in expr and factor) would solve this nicely. So either the sizeof test is insufficient, or there are other bugs (I suspect the latter). For now, I may just sweep this under the rug and skip the test on systems without glibc. Alternative patches welcome. _______________________________________________ Bug-coreutils mailing list [email protected] http://lists.gnu.org/mailman/listinfo/bug-coreutils
