Recall that in MSVC, enums are always signed ints by default. Clang gives you this: ..\tools\clang\include\clang/Sema/ScopeInfo.h(616,10) : warning: implicit truncation from 'clang::sema::FunctionScopeInfo::ScopeKind' to bitfield changes value from 3 to -1 [-Wbitfield-constant-conversion] Kind = SK_CapturedRegion; ^ ~~~~~~~~~~~~~~~~~ ..\tools\clang\include\clang/Sema/ScopeInfo.h(714,10) : warning: implicit truncation from 'clang::sema::FunctionScopeInfo::ScopeKind' to bitfield changes value from 2 to -2 [-Wbitfield-constant-conversion] Kind = SK_Lambda; ^ ~~~~~~~~~ I guess I'll bump it to 3 bits.
