/* Versions:
 *     gdb version 3.1; gcc version 1.35
 * File:
 *     <this file>
 * Problem:
 *     `gdb' doesn't understand variable length arrays (an extension provided
 *     by `gcc').
 * Repeat by:
 *     % gcc -g <this file> -o bug
 *     % gdb -q bug
 *     Reading symbol data from /usr/sumatra/people/derek/gnu/gdb/bug...done.
 *     (gdb) break foo
 *     Ranged type doesn't fit within known sizes.
 *     (gdb) quit
 *
 * Notes:
 *     `gdb' was compiled with `config.gdb sun3os4'.
 *     `gcc' was compiled with `config.gcc sun3-os4'.
 *     I am using a Sun 3/60 with UNIX 4.2 (Sun release 4.0.1).
