Then, IMHO, you should reopen the bug. I bet it's a Makefile bug related to parallel building, because my autobuilders are single-CPU and I also have this in my .sbuilrc file: $ENV{'DEB_BUILD_OPTIONS'} = 'parallel=1'; and gcc-5 builds ok for me. Can you try putting that in .sbuildrc and see if the problem disappear? That would confirm that it's a Makefile bug, I think. Thanks.
