Re: Problem debugging core dump in gdb 7.1 on Solaris x86_64

[Max Kaehn <slothman at electric-cloud dot com>]

Even dbx has trouble with it; this may be more of a Solaris issue than a 
gdb one.  This is running the debugger on the same machine as the core 
dump, and it still has issues:

Use `help core mismatch' for more info.
