| 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. |
