It's possible that these failures existed all along. But they look like either a piece of the stack or some relevant registers are not getting scanned. The failure seems to occur without triggering any assertion failures, even after adding the fairly expensive assertion here. They seem to generally occur in reverse_test, but may occur during manipulation of data referenced only by the stack. Static root finding doesn't seem to be the issue.

I don't observe any test.c failures with CVS [+ win32_threads.c.diff] compiled with VC++ 2005/2008 (NT_STATIC_THREADS_MAKEFILE).
