Jim (& Chris),

No, the command line was fine. But I understand why now...

Those log files were very helpful--I wasn't aware of those before. The stack track in there made it clear it was indeed trying to open a user routine somewhere. dtrace helped me ID a 'test.sav' that was trying to be loaded from the IDLWorkspace84/Default directory, which is why it was only crashing in eclipse--that directory isn't added to the command line IDL path by default.

Trying the same thing from the command line with that file in the path does then give the same result, with a bit more error output:

IDL> test
% Wrong number of tags defined for structure: LIST.
% Structure not restored due to conflict with existing definition: LIST.
Segmentation fault: 11

The file contained an old save of an object that does contain some LISTs buried in it's property hierarchy.

Restoring the file does not crash IDL:

IDL> restore,'./test.sav'
% Wrong number of tags defined for structure: LIST.
% RESTORE: Structure not restored due to conflict with existing definition: LIST.
% Wrong number of tags defined for structure: LIST.
% RESTORE: Structure not restored due to conflict with existing definition: LIST.
% Wrong number of tags defined for structure: LIST.
% RESTORE: Structure not restored due to conflict with existing definition: LIST.

Looks like the save was in IDL 8.2.3. Did LIST's data structure evolve since then?

None of this is critical for me to restore/retain... mostly morbid curiosity at this point. But let me know if it's useful to poke around further to characterize a bug.

- Matt
