That sounds more like paranoia than reason.  

Unsurprisingly all "show version" does is output the version of GDB:

address@hidden:~$ gdb -q
(gdb) show version
GNU gdb 6.8-debian

This GDB was configured as "x86_64-linux-gnu".
(gdb) 

That's the same text that is output if "-q" isn't specified.

Unlike other commands, it doesn't change the state of the executable or the
debugger.  Parsing the output is no different in it's nature to the the many
other lisp functions that already do this except that some of those _do_
change the state of the executable or the debugger

I don't think that should really be necessary.

Likewise it's not that important to me either: I don't currently use a Mac.  I'm
just trying to react to the bug reports that have been made.
