sshd 7.4p1 with ssl 1.0.2j seg faults, MacOSX 10.12.2/3, clang-800.0.42.1

[Zube]

Never had much trouble building on the Mac until this round.

Trying to build 7.4p1 with openssl 1.0.2j on a MacOSX 10.12.2/3
machine.  gcc --version returns clang-800.0.42.1.  This is the
latest Xcode.

Builds fine.  Upon running sshd, it seg faults with this in the logs:

assertion failed 16C67:  libsystem_trace.dynlib+76912
[5BD4ECD4-75CA-38EA-AF5C-B481C15955F8]: 0x0

If I run the tests, it fails in:

test_utf8

regress/unittests/utf8/tests.c:  51
test #9  "utf8_inv_badbyt"

ASSERT_INT_EQ (len, wantlen) failed:
  len = 2
  wantlen = 5

/bin/sh:  line 1:  739  Abort trap: 6.

Thank you for your time and for any clues.

Cheers,
Zube
