Public bug reported: Porting a particular build of v8 from ubuntu 17.10 to ubuntu 18.04 circa beta 2, its make failed at -j2, but succeeded at -j1. The error message was odd:
... make[3]: Entering directory '/home/buildbot/src/oblong-v8/out/v8/out' testing/gtest.target.x64.release.mk:229: warning: overriding recipe for target '/home/buildbot/src/oblong-v8/out/v8/out/x64.release/libgtest.a' testing/gtest.host.x64.release.mk:221: warning: ignoring old recipe for target '/home/buildbot/src/oblong-v8/out/v8/out/x64.release/libgtest.a' make[3]: Leaving directory '/home/buildbot/src/oblong-v8/out/v8/out' make[3]: *** read jobs pipe: Success.

This is on a machine with 32GB of RAM. The problem reproduces quickly and reliably. Happy to try other versions of make and/or provide more data. ** Affects: make (Ubuntu) Importance: Undecided Status: New ** Attachment added: "apport report" https://bugs.launchpad.net/bugs/1761932/+attachment/5105088/+files/apport.make.tkkb4vy9.apport -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1761932 Title: make -j2 aborts with "make[3]: *** read jobs pipe: Success.
