Subject: tests: head-c: avoid spurious failure with a 32-bit size_t
X-Git-Tag: v8.22~134
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=aeaeb87c134ce748527ba99e749b7369fcba2438;p=thirdparty%2Fcoreutils.git

tests: head-c: avoid spurious failure with a 32-bit size_t

* tests/misc/head-c.sh: Don't try to elide 1 exabytes, since on
32-bit systems, that number is not representable as a size_t.
This command would fail on 32-bit systems, where SIZE_MAX < 1E:
  head --bytes=-E < /dev/null
Instead of "E", use $SSIZE_MAX.
For discussion, see http://bugs.gnu.org/13530
