Regarding "debugged", it would be a nice start if people listening on
this mailing list would help out as requested.  Please attach to the
ticket a preprocessed testcase (a *.i file obtained from gcc with the
--save-temps option) and the output of adding -### to the gcc
invocation.  Bugs aren't fixed magically, I tried making a simple
testcase and failed.
