3 sandbox_linux_unittests failing on UbsanVptr |

Issue descriptionNamely: SandboxBPF.SyntheticPolicy SandboxBPF.UnsafeTrapWithCond SandboxBPF.ApplyBasicWhitelistPolicy https://luci-milo.appspot.com/buildbot/chromium.fyi/ClangToTLinuxUBSanVptr%20tester/1447 [ RUN ] SandboxBPF.SyntheticPolicy ../../sandbox/linux/tests/unit_tests.cc:260: Failure Expected: kExpectedValue Which is: 42 To be equal to: subprocess_exit_status Which is: 1 Actual test failure: ==-10==ERROR: UndefinedBehaviorSanitizer failed to allocate 0x1000 (4096) bytes of InternalScopedBuffer (error code: 3) ==-10==Sanitizer CHECK failed: /b/c/builder/ClangToTLinuxUBSanVptr/src/third_party/llvm/compiler-rt/lib/sanitizer_common/sanitizer_procmaps_common.cc:78 ((proc_self_maps_.len)) > ((0)) (0, 0) The builder's been red for a long time, so not clear when this started. Started in https://luci-milo.appspot.com/buildbot/chromium.fyi/ClangToTLinuxUBSanVptr%20tester/1370 maybe, but no clear fault. Error message kind of looks like this might be a ubsan runtime thing?
