Looks like a the locks.lib is corrupt. When I rebuild locks.lib without -O passed to the compiler everything works fine. That would explain why my unittests passed when I last updated it. I have updated the zip file with a locks.lib built without -O and I'll try to narrow down the problem to post to D.bugs for Walter to ponder. -Ben
