Yes, I get the same thing on IDL 8.0.1 on my Mac.

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
% Error occurred at: $MAIN$
% Execution halted at: $MAIN$
IDL> openr,1,'foo'
idl(7687,0x7fff710b8ca0) malloc: *** error for object 0x10060441d:
pointer being freed was not allocated
*** set a breakpoint in malloc_error_break to debug
Abort trap
