New Revision: 274143
URL: https://svnweb.freebsd.org/changeset/base/274143
Log:
Expect lib.libc.sys.getcontext_test.setcontext_link to fail on amd64; add
additional debugging to make the underlying problem more visible
Calling setcontext(2) on amd64 as shown in the test program is failing on
amd64, not i386, with a return code of -1 and an errno of EINVAL
Further investigation is being done in the PR to determine the root cause for
the failure
PR: 194828
Tested with the following configuration:
- amd64/i386
- 11.0-CURRENT @ r273153
- 100 times in a tight loop as root with the following commands...
-- kyua test lib/libc
-- kyua test lib/libc/sys
-- kyua test lib/libc/sys/getcontext_test
