I posted about this 5 days ago on ppc list [1], but have had no response. I tried to get some attention on #fedora-ppc today, also with no success. I am failing miserably to get the attention of any of the PPC folks, so I am trying email here to see if this will work.
GCL is failing to build sometimes on ppc64/ppc64le. I have had both successful [2] and unsuccessful [3] builds. Both of those build logs contain lots of extra debugging junk I threw in so I could gather information on what is going on. Here's the critical part. The "uname -a" invocation I added at the top of %build always shows a 3.14 kernel when the build succeeds and always shows a 3.16 kernel when the build fails.
I believe there is a bug in the 3.16 ppc64/ppc64le kernels on (some of?) the builders. The bug, whatever it is, is causing spurious mprotect() failures. If somebody can either confirm or deny that, I am very interested. I have not had this problem on any other architecture. Thank you.

Still nothing. Can anybody help me get the attention of somebody on the PPC team?

Then at least say:
We are aware of this, but don't have a solution yet.
Leaving people hanging only makes it worse.

Dan, is there a bug reference ?
