-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.
