The compiler does not get far enough to generate a *.i file.  I am pasting the
file "bug1.F90" below and attaching.

Thank you, -John

I have built the top of the new GCC repository (c71644776f, dated today) and
verified that the bug is in fact fixed. I am marking the ticket as resolved.
Thank you for the quick and helpful reply. Best regards. -John
