From d0c138ec8aa47ec2acb38dba247f537ca470618f Mon Sep 17 00:00:00 2001 From: Dmitry Vyukov Date: Tue, 16 Nov 2021 14:45:07 +0100 Subject: [PATCH] tsan: disable bench_threads.cpp on aarch64 The new test started failing on bots with: CHECK failed: tsan_rtl.cpp:327 "((addr + size)) <= ((TraceMemEnd()))" (0xf06200e03010, 0xf06200000000) (tid=4073872) https://lab.llvm.org/buildbot#builders/179/builds/1761 This is a latent bug in aarch64 virtual address space layout, there is not enough address space to fit traces for all threads. But since the trace space is going away with the new tsan runtime (D112603), disable the test.
