Recent Clang versions fixed a bug which had previously allowed some casts that removed qualifiers to go undiagnosed. This fixes the following kind of error: ./../third_party/webrtc/api/optional.h:41:35: error: reinterpret_cast from 'const int *' to 'void *' casts away qualifiers FunctionThatDoesNothingImpl(reinterpret_cast<void*>(x))); ^~~~~~~~~~~~~~~~~~~~~~~~~~ ../../third_party/webrtc/api/optional.h:280:45: note: in instantiation of function template specialization 'rtc::optional_internal::FunctionThatDoesNothing<const int>' requested here return has_value_ ? *optional_internal::FunctionThatDoesNothing(&value_) ^ ../../third_party/webrtc/call/rtp_bitrate_configurator.cc:70:53: note: in instantiation of member function 'rtc::Optional<int>::value_or' requested here std::max(bitrate_config_mask_.min_bitrate_bps.value_or(0), ^ Bug: chromium:831081 Change-Id: I032ebd1f052fa2a50548e984febb7fa462df42ea Reviewed-on: https://webrtc-review.googlesource.com/68941 Commit-Queue: Hans Wennborg <hans@chromium.org> Reviewed-by: Karl Wiberg <kwiberg@webrtc.org> Cr-Commit-Position: refs/heads/master@{#22804}
