Race between TestCpuFlag and InitCpuFlags
GoogleCodeExporter opened this issue · comments
Two concurrent initial runs of TestCpuFlag() race since cpu_info_ == kCpuInfo
is checked/set without proper atomics.
Are we required/supposed to call libyuv::InitCpuFlags() before concurrent uses
of libyuv to avoid undefined behavior/myriad of errors? It looks like an
internal-only function.
Hitting this in webrtc using ThreadSanitizer. We have multiple receivers
running concurrently, hence the race during Decode(). Repro stacks below:
