--- Comment #19 from Gary Funck <gary at intrepid dot com> ---
We see similar failure an x86-64 opensuse VM in the 32-bit libgfortran build
but on a different file: eoshift.c.  After removing the .lo and .o files and
re-running make, the build completed without error.  As described in earlier
comments, this issue is not easily reproducible.
