https://bugzilla.mindrot.org/show_bug.cgi?id=2301

            Bug ID: 2301
           Summary: test_sshbuf_misc.c:44 ASSERT_INT_NE(feof(out), 0)
                    failed
           Product: Portable OpenSSH
           Version: 6.7p1
          Hardware: MIPS
                OS: IRIX
            Status: NEW
          Severity: enhancement
          Priority: P5
         Component: Regression tests
          Assignee: unassigned-bugs at mindrot.org
          Reporter: openssh at canavan.de

When compiled with -g0, test_sshbuf dies with an assert on IRIX 6.5.30:

test_sshbuf:
.....................................................................................
regress/unittests/sshbuf/test_sshbuf_misc.c:44 test #86 "sshbuf_dump"
ASSERT_INT_NE(feof(out), 0) failed:
   feof(out) = 0
           0 = 0
/bin/sh[2]: 73136 Abort


when compiled with Optimizations (I've only tried -O3), the test dies
with a segfault:

test_sshbuf:
.....................................................................................Process
83095 (test_sshbuf) stopped on signal SIGSEGV: Segmentation violation

--- Comment #1 from Damien Miller <djm at mindrot.org> ---
This is probably due to Irix's libc not support the %z format
characters.

Does the autoconf-generated config.h define BROKEN_SNPRINTF on your
platform?
