--- Comment #1 from Sam Warner <Samuel.r.warner at me dot com> ---
I should add that when I use GDB where I put the application to be debugged on
the command line of a Terminal within OS-X, everything functions flawlessly. 
It's only when I use the "file" command or the equivalent GDB/MI command that
the 'null pointer" issue shows up.

( GDB app in my install has been fully enabled to execute with 'code signing'
instructions.)

What prompted my investigation in narrowing down the problem was the GDB/MI
seemed to be having some issue, later I found it was simply the 'file' command.

Looks like a duplicate of https://sourceware.org/bugzilla/show_bug.cgi?id=26912
(and https://sourceware.org/bugzilla/show_bug.cgi?id=27365).
