Subject: Fix SpecificBumpPtrAllocator iteration.
X-Git-Url: http://plrg.eecs.uci.edu/git/?p=oota-llvm.git;a=commitdiff_plain;h=86bfd34ece523d863282ef2a2e4cf451c387c559;ds=sidebyside

Fix SpecificBumpPtrAllocator iteration.

Need to start from (char*)(Slab+1), and not from (char*)Slab+1.
This fixes crashes in Win64 debug mode.
Thanks to Nicolas Capens!
