It was still sitting in my ever-longer queue; sorry.

I think a fix for this issue would be a lot easier for me together with
a testcase (along the lines of HEAD's tests/template.at) that exposes
this issue.  A small self-contained (portable!) example would be a good 
start.  This helps ensure that we don't regress with other unrelated
compilers.  (And testing will then allow me to evaluate whether the
patch Peter suggested is good enough.)

Thanks,
Ralf
