          Hardware: x86-64
                OS: Mac OS X

secur32:negotiate & secur32:ntlm crash from a NULL dereference on macOS:

Unhandled exception: page fault on read access to 0x0000000000000008 in 64-bit
code (0x0000017004f9ed).

Initially this looked like the same issue as secur32:secur32 (bug 55555), i.e.
a missing libkrb5 library. But changes were made for that library and that test
no longer crashes on macOS so this must be another issue. Also other secur32
test units don't crash.
