--- Comment #12 from Alexandre Oliva <aoliva at gcc dot gnu.org> ---
FTR, the installed patch does not fix the reported problem, but rather another
problem that had surfaced after the report, that affected the (preprocessed)
workaround testcase.  GCC remains unable to compile the original testcase.
