How about rewording “Fix various non-unified build issues introduced since r251436”? > > Source/JavaScriptCore/runtime/ObjectInitializationScope.h:32 > > +#ifdef NDEBUG > > +#include "VM.h" > > Let's try to avoid protecting #includes with #ifdef NDEBUG, because that > would lead to strange debug-only or release-only build failures. I will remove the guards before landing. Thanks for the review!

Can you provide some details about why VM.h is needed here? What is the error?

What is the > error? The reason I ask is because VM.h is a heavy-weight file, and I'm always wary when we #include it in yet another header file. Just wondering if there are any cheaper solutions for this.

The error is caused from the access to “m_vm” in the ~ObjectInitializationScope() destructor, so I think there is no way around including “VM.h” unless we move the destructor to the .cpp file — probably a bad idea as it is marked with ALWAYS_INLINE (when -DNDEBUG is in use → no debugging → release builds). The compiler error is: In file included from ../Source/JavaScriptCore/runtime/ObjectInitializationScope.cpp:27: ../Source/JavaScriptCore/runtime/ObjectInitializationScope.h:46:13: error: member access into incomplete type 'JSC::VM' m_vm.heap.mutatorFence(); ^ ../Source/JavaScriptCore/runtime/ArrayBuffer.h:42:7: note: forward declaration of 'JSC::VM' class VM; ^ 1 error generated.

Thanks. Go ahead and #include it for now. We can look at an alternative solution later if needed.
