Subject: Initialize the PoisonMemory member before initializing
X-Git-Url: http://plrg.eecs.uci.edu/git/?a=commitdiff_plain;h=5b78d50cadf5df4948e8e5798a3e08e0ccf4cb06;p=oota-llvm.git

Initialize the PoisonMemory member before initializing
members that call methods that read the PoisonMemory member.
This fixes potential spurious (though probably otherwise
harmless) poising of unused memory, and fixes the
associated valgrind error.
