It'd be nice to just let the compiler generate this and not define it explicitly at all.

Committed r60258: <http://trac.webkit.org/changeset/60258>

http://trac.webkit.org/changeset/60258 might have broken GTK Linux 32-bit Release and Qt Linux Release
The following changes are on the blame list:

This looks to have introduced a crash in fast/dom/prototype-inheritance-2.html.

I see the crash on the following bots:
* Chromium (linux, win, mac)
* Leopard Intel Debug (Tests)
* Snow Leopard Intel Leaks

[Darin Adler]

Is there a URL for the backtrace from the crash?

[Anders Carlsson]

I think that the crash was caused by another change - looks like Geoff fixed it in http://trac.webkit.org/changeset/60261

[Julie Parent]

Here is the Chromium linux bot stack:
	StackTrace::StackTrace() [0x80eeacf]
	base::(anonymous namespace)::StackDumpSignalHandler() [0x80de9da]
	0x4001c420
	WebCore::collectionIndexedPropertyEnumerator<>() [0x89648a8]
	v8::internal::GetKeysForIndexedInterceptor() [0x81ba92e]

Geoff's change was fixing a different crash.

Looks like there may be new failures on Qt after this change?

It seems this patch broke tests. I try to roll-out it locally now to confirm it.

The crashing of fast/dom/prototype-inheritance-2.html also occurred during my WebKit gardening. I submitted and committed a quick fix in WebKit r60276.
