=== *Description* ============================================================
Running VSC 5.2.13 on OpenSolaris based on snv_127 showed some failures for
/POSIX.cmd/cmp tests assertions 14, 15 and 18. The error message written to the
journal file is identical for all 3 assertions. An example is shown below:
520|70 15 25221 1 1|Assertion #15 (A): Verify output of ga66.
520|70 15 25221 2 1|Expected exit code = 0; Received 1
220|70 15 1 22:41:36|FAIL
410|70 15 1 22:41:36|IC End

This is not an error in AST "cmp", this is IMO a bug in the test suite.
Glenn Fowler from AT&T explained the issue in one of his postings:
-- snip --
the VSC tests for the other assertions [Glenn refers to the assertions
reported in CR #6904808] are flawed. They assume that cmp must always
read the input files and thus touch the st_atime but in the case where
both files are the same cmp can exit 0 after just a stat() of each file
it produces the correct result but does not cause any stat() field of
the input files to change.
-- snip --
BTW: GNU "cmp" and BSD "cmp" use the same optimisation (and therefore
will not change the access timestamp and therefore fail these tests,
too).
AFAIK this bug should be closed and a bug report against VSC needs to be
filed.
