>Description:

The following tests are failing both on real amd64 hardware and on
qemu; the ones without "32" in the name are also failing on i386:

  usr.bin/c++/t_cxxruntime/cxxruntime_pic_profile
  usr.bin/c++/t_cxxruntime/cxxruntime_pic_profile_32
  usr.bin/c++/t_static_destructor/static_destructor_pic_profile
  usr.bin/c++/t_static_destructor/static_destructor_pic_profile_32

For recent logs, see:

  http://www.gson.org/netbsd/bugs/build/amd64-baremetal/2019/2019.02.21.14.56.23/test.html#failed-tcs-summary

The i386 failures were automatically reported to current-users on
Feb 18, but because they appeared during an extended period when the
system did not build and/or boot, the pool of commits that could have
caused them is large:

  From: NetBSD Test Fixture <bracket%NetBSD.org@localhost>
  To: current-users%NetBSD.org@localhost
  Subject: Automated report: NetBSD-current/i386 test failure
  Date: Mon, 18 Feb 2019 00:45:16 +0000 (UTC)

  This is an automatically generated notice of new failures of the
  NetBSD test suite.

  The newly failing test cases are:

      usr.bin/c++/t_cxxruntime:cxxruntime_pic_profile
      usr.bin/c++/t_static_destructor:static_destructor_pic_profile

  The above tests failed in each of the last 3 test runs, and passed in
  at least 27 consecutive runs before that.

  Between the last successful test and the failed test, a total of 412
  revisions were committed, by the following developers:

      christos
      gutteridge
      hannken
      isaki
