Test failure on Serialization/complex.c?

I'm currently seeing a failure on Serialization/complex.c: glibc
detected *** clang: corrupted double-linked list: 0x086896d0 ***.

Does anyone else see this? I don't think I have any changes in my
tree that could cause this, although I'll look more closely if nobody
else is seeing this.


Thanks for fixing this. This failure didn't show up on Mac OS X.
