lang/node hangs quite often during build on i386: 20180926 20181001 (twice) 20181105 20181217 (twice) 20190115 20190218
As this is on the path to chromium, iridium and firefox that's quite annoying in a bulk build. I started logging build restarts around February 2018 and didn't have any until 20180926, which is around the time of the 8.12.0 update. End of the log from the last one shows that is using -O3 and not honouring CFLAGS/CXXFLAGS. Can't say if there might be a problem with -O3 but that might be an easy first thing to try .. Otherwise, any ideas about how to get some information out of this? The problem is that this breakage isn't usually visible until after DPB has already killed the build, so there's no process I can ktrace or attach gdb to .. (I suppose I could remove stuck_timeout if there are no better ideas, but that will make builds even slower when things hang - node isn't the only one, but it's probably the most frequent at the moment, and certainly the most annoying :) [...] c++ -o /usr/obj/ports/node-10.15.0/node-v10.15.0/out/Release/obj.host/v8_libbase/deps/v8/src/base/logging.o ../deps/v8/src/base/logging.cc
