I get 
[prt@localhost prs]# /svn-4.2/bin/gfortran pr27897.f90
 In file pr27897.f90:2

  common /i/ x
           1
Error: Symbol '&#65533;!z      &#65533;!z     ' at (1) is already an external
symbol that is not COMMON

... so it is trying to do the right thing but the symbol name is wrong.

Thank you for the report - I hope that you can refrain from giving your main
program and common blocks the same name for a while!

Paul

Iguchi-san,

The error is at line 2296 of match.c; a sym->name is used, where sym is not yet
defined.  It should just be the parsed name, "name".

I wil submit a patch in the next day or so (I am trying to get a backlog out of
the door.).

Thanks again

Paul
