Weak external symbols found when building with Release+Coverage configuration:

PhaseScriptExecution Check\ For\ Weak\ VTables\ and\ Externals JavaScriptCore.build/Release/JavaScriptCore.build/Script-5D29D8BE0E9860B400C3D2D0.sh
    cd OpenSource/Source/JavaScriptCore
    /bin/sh -c JavaScriptCore.build/Release/JavaScriptCore.build/Script-5D29D8BE0E9860B400C3D2D0.sh
ERROR: JavaScriptCore has a weak external symbol in it (Release/JavaScriptCore.framework/Versions/A/JavaScriptCore)
ERROR: A weak external symbol is generated when a symbol is defined in multiple compilation units and is also marked as being exported from the library.
ERROR: A common cause of weak external symbols is when an inline function is listed in the linker export file.
ERROR: symbol ___llvm_profile_filename
ERROR: symbol ___llvm_profile_raw_version
ERROR: symbol _lprofDirMode
Command /bin/sh failed with exit code 1
