Subject: [libFuzzer] don't disable msan for TracePC::CollectFeatures: this started to cause... 
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=8330752796bc21460dcdbacaa4a7dcd7fa367b3f;p=llvm

[libFuzzer] don't disable msan for TracePC::CollectFeatures: this started to cause false positives in msan. No tests for libFuzzer+msan yet -- tests will need to wait until we move libFuzzer to compiler-rt
