--- Comment #2 from David Binderman <dcb314 at hotmail dot com> ---
I also see this problem while trying to build file libgfortran/caf/single.c 
with compiler flag -O3 on revision 277600.

I'll have a go at a workaround of using -O2 on the bootstrap.

I suspect a useful weekly sanity check would be a bootstrap with
-O3 over c,c++ and fortran.

Martin's code snippet compiles fine with revision 277550 and -O3,
so the new problem looks recent.
