diff gen/runtime.cpp @ 1328:c78fd2d30da1
Changed array slice copying to call a runtime function when assertions or array bound checks are enabled instead of just doing a memcpy. This makes sure an exception is thrown if the copy is invalid (ie. different lengths or overlap). Fixes ticket #283 . Rebuilding the runtime is necessary.
