AIX: Test failures - malloc(0) #7549

• Version: master
• Platform: AIX
• Subsystem:

Now that AIX is building again after recent build breaks there are 4 failing tests:
https://ci.nodejs.org/job/node-test-commit-aix/nodes=aix61-ppc64/244/

Some of them look potentially related to: #7229.

Will need to investigate to see if its new or a regression.
