libhugetlbfs test suite failed with brk_near_huge test

This bug is missing log files that will aid in diagnosing the problem. From a terminal window please run:

apport-collect 1653597

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

This failure can be found on Xenial kernel 4.4.0-58.79 on gce as well.

I can't collect information as I don't have access to cloud instances yet.

This bug also affects the -azure kernel:
http://kernel.ubuntu.com/testing/4.10.0-1005.5-azure/libhugetlbfs-4.10.0-1005.5-x86_64%20(azure)-index.html

Also seen on 4.11 in artful. The assertion seems to be related to internal heap bookkeeping, so likely a glibc error or heap corruption and not a kernel problem.

For the record, it's found on linux-azure 4.11.0-1003 as well.

This appears to be related to Azure giving the context of the bug, tagging as such, next is this still an issue to date? if not, has there been a test generated to test for this specific issue in the future? or can we forget it?

This issue still exists for 4.15.0-1019.20~16.04.1-gcp [1](every nodes for GCP) and 4.15.0-1022.22~16.04.1-azure [2] (some nodes for Azure)

I just looked at the test results for this test suite across some GCP cloud instances and it looks like it's failing across the 4.15 kernels.
