…it.org/show_bug.cgi?id=255951 rdar://108261913 Reviewed by Alexey Shvayka and Justin Michaud. 1. MarkedVector::fill is not registering itself as a strong root of GC. This patch fixes it with m_markSet->add. 2. Initialize buffer with empty value in MarkedVector::fill. This buffer can be scanned via GC when GC is invoked from a passed lambda. * JSTests/stress/marked-buffer-fill-should-be-gc-aware.js: Added.
