Hello,

This test:

- runs a program that allocates a bit of memory
- lets the program dump core
- compares the corefile against a a running version of the program

On my i386 GNU/Linux system I'm seeing the failure:

> KFAIL: gdb.base/bigcore.exp: check heap (address 0xb7449008) (PRMS: gdb/1509)
> 
>                 === gdb Summary ===
> 
> # of expected passes            7
> # of known failures             1

from:

> (gdb) print $.next
> $55 = (struct list *) 0x400c0490
> (gdb) print $.next
> $56 = (struct list *) 0xbffc6008
> (gdb) print $.next
> Error accessing memory address 0xbffc6008: Invalid argument.
> (gdb) KFAIL: gdb.base/bigcore.exp: check heap (address 0xb7449008) (PRMS: gdb/15

which I suspect is due to the core file being a little big:

$ du -b bigcore.corefile
282624  bigcore.corefile
$ ls -l bigcore.corefile
-rw-------    1 cagney   cagney   3084910592 Jan 13 21:21 bigcore.corefile

and gdb having difficulty accessing the 2nd gb.

Given that people might want a bit of time to digest this (on some 
systems may not be so efficient at dumping core files making the test 
too slow) I'll follow this up in a week.

enjoy,
Andrew
