Details:

When octave compiled with clang and llvm's libc++ library 
(which is usually the case on macOS), the test general/logspace.m
fails:


octave:1> test  general/logspace.m
***** assert (logspace (Inf + 1i, Inf + 1i, 3), repmat (complex (-Inf,Inf),
[1, 3]))
!!!!! test failed
ASSERT errors for:  assert (logspace (Inf + 1i, Inf + 1i, 3),repmat (complex
(-Inf, Inf), [1, 3]))

  Location  |  Observed  |  Expected  |  Reason
    (1)        Inf+NaNi    -Inf+Infi     'NaN' mismatch
    (2)        Inf+NaNi    -Inf+Infi     'NaN' mismatch
    (3)        Inf+NaNi    -Inf+Infi     'NaN' mismatch


This particular case is on Fedora 29, clang 7.0.1 libc++ 7.0.0.
hg id ada14ef3067f (stable)

The test passes when octave compiled with clang and libstdc++.

Dmitri.
