test-tick-processor failures on PPC #2957
Description
The test-tick-process test fails on PPC
https://ci.nodejs.org/job/iojs+pr+ppc/nodes=ppcbe-fedora20/18/console
We have debugged the problem to the point were we believe the issue is due to PPC 64 BE using function descriptors (as does AIX 64 and 32 were we see the same problem). The issue seems to be on the V8 side where it only adds symbols in address ranges marked executable which is not the case for function descriptors. If we remove that check the test passes. We are still looking at how best to address the issue.

We are still looking at this one and trying out some alternatives for how to fix on the v8 side
mhdawson commentedon Oct 13, 2015
We are still working to put together change that resolves this

FYI, put this in place while we continue to investigate: #3491

Latest update:
part of the fix in via https://chromium.googlesource.com/v8/v8.git/+/2bd5914bc3ae8c01c115f0386ae91c9f341c7ccb
Still remaining is a modification to the post processing script to look at the .opd section when gathering symbolic information

More complete disable for AIX, noting to make sure we remember to revert once fix is in
#5093

Closing as I think #5093 addressed this more-or-less, test-tick-processor has been broken into three different test files now, and remaining flakiness is being explored in #8725. (Re-open or comment if you think this shouldn't be closed.)
