When doing a build from scratch (or a non-update build) on my 8-core amd64 build host, 'make' consistently stalls when building:

A followup update build proceeds to completion. This happens on all target architectures I build (amd64, i386, sparc, sparc64, prep, mvme68k, amiga, macppc, mac68k, evbearmv7hf-el). It seems to only happen on machines with multiple real CPUs/cores. A single-processor hyperthreaded machine doesn't stall. It seems to be a quirk of -current tools. Building for netbsd-7 from scratch doesn't stall. -- |/"\ John D. Baker, KN5UKS NetBSD Darwin/MacOS X |\ / jdbaker[snail]mylinuxisp[flyspeck]com OpenBSD FreeBSD | X No HTML/proprietary data in email.
