Created attachment 382154 [details] build.log Please see the attached build.log. Would stabilizing 4.x (bug 512188) on amd64 solve the issue perhaps?
I can reproduce this. It looks like either a newer gcc or newer boost is causing this. I'd prefer to "fix" this with a stable 4.x version (where this is fixed), rather than backporting the fixes to 3.x.
passenger 3.x has been removed, and I have not seen similar reports for passenger 4.x versions.
