+ WebContent crash in WebCore::MemoryPressureHandler::releaseCriticalMemory() with GuardMalloc when preparing to suspend
+ https://bugs.webkit.org/show_bug.cgi?id=149350
+
+ Reviewed by Antti Koivisto.
+
+ in MemoryPressureHandler::releaseCriticalMemory(), iterate over a copy of
+ Document::allDocuments() instead of iterating over allDocuments() directly.
+ Also make sure the Documents are ref'd inside the copy.
+
+ This is needed because clearing the StyleResolver of a Document may cause
+ Documents to be unref'd and removed from the allDocument() HashSet.
+
+ No new tests, already covered by existing tests.
