Summary: Currently, the SafeStack analysis disallows out-of-bounds writes but not out-of-bounds reads for mem intrinsics like llvm.memcpy. This could cause leaks of pointers to the safe stack by leaking spilled registers/ frame pointers. Check for allocas used as source or destination pointers to mem intrinsics.
