Hi all,
I was able to get the following to crash IDL 8.0.1 on a 64-bit Mac
running OSX 10.6.6:

MacBook:bin chris$ idl
IDL Version 8.0.1 <Integration build Thu Jul 29 18:17:29 MDT 2010>,
Mac OS X (darwin x86_64 m64).
(c) 2010, ITT Visual Information Solutions
Installation number: 000015.
Licensed for use by: ITT ONLY

IDL> system_var_file = '/tmp/system.sav'
IDL> save,/system,file=system_var_file
IDL> restore,system_var_file
IDL> openr,1,'foo'
% OPENR: Error opening file. Unit: 1, File: foo
No such file or directory
% Execution halted at: $MAIN$
IDL> openr,1,'foo'
idl(17500,0x7fff70ce2ca0) malloc: *** error for object 0x100603595:
pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Abort trap

Notice that you have to call the "openr" twice before it crashes.

Can someone try the above code on their machine, and see if it also
fails?

I'll go ahead and log a bug, and we'll see what we can do. Thanks for
finding this!
