Bug description
Starting from a large program with many dependencies that began segfaulting unpredictably shortly after we added use of weak pointers, I have come up with a one-page example that reliably triggers a segmentation fault (or other nasty fault) with 3.10.1+dev0 on both ia32 and amd64 Linux. Making small changes like manual inlining of functions changes whether or not the crash occurs, so I think it is almost certain that memory corruption is occurring.
