C I sent the following to fortran@gnu.ai.mit.edu, and Dave Love
C replied that he was able to reproduce it on rs6000-aix; not on
C others. He suggested that I send it to egcs-bugs. 
 
C Hi - I've observed the following behavior regarding 
C automatic arrays and gotos.  Seems similar to what I found
C in the docs about computed gotos (but not exactly the same).
C 
C I suspect from the nature of the error msg that it's in the GBE.
C 
C I'm using egcs-971105, under linux-ppc.
C 
C I also observed the same in g77-0.5.19 (and gcc 2.7.2?).
C 
C I'd appreciate any advice on this.  thanks for the great work.

C If I comment out the b(n) line or replace it with, e.g., b(10),
C it compiles fine.
