I saw your message after I sent mine. How exactly is it supposed to
work? I can't reliably repro the condition that leads to the variable
being inherited across buffers (even with Torsten Bronger's testcase),
so I can't test it. It doesn't seem like adding a DEFSYM should make a
difference here though. Can you explain why your patch works?
