What have you tried to solve it?

Ran on Linux server and there was no issue.

Hi @apeforest Does this fail in CI?

@mxnet-label-bot could you please add [gluon, test] to this issue?

[apeforest]

@marcoabreu Any update on this unit test? This unit test failure on MacOS has caused inconvenience to verify the unittest locally before pushing my change to remote. Any other people who develop on MacOS facing the same issue?

Hi @apeforest, did you use gcc on Mac? Which version?

[apeforest]

@lanking520 We currently don't run MacOS platform in CI, which I think should be installed ASAP.

MacOS is now installed on the CI via Travis.
