[comp.sys.mac.system] Finder crashes when resolving alias

tonym@polari.UUCP (Tony Mann) (06/24/91)

Sometimes the Finder crashes with an Illegal Instruction error when
resolving an alias through the "Find Original" button.  I am not sure
what conditions lead to the crash.

Has anyone else experienced something similar?  If so, have they determined
what conditions cause it?

I am using an SE/30 . I want to get to the bottom of this!

Happened to me twice. Not enough to discover a pattern. The first time
I didn't do anything strange (except for pressing 'find original'), the
second time it happened after I did something naughty:

To find out how some of the Finder's new control panels work (they do
not contain any code!) I changed the type/creator of a random
application to the type/creator of the views control panel. Indeed, the
application, when double clicked, behaved exactly like the views
control panel. There was an alias to the application of which I changed
the type/creator, and the Mac crashed when trying to find the
original (from the Get Info window).

When I changed the type/creator back, everything was normal again.

Thinking about this... Maybe it goes wrong
a) when a certain type/creator combination isn't unique, or
b) when the type/creator of an alias's original is changed...

or something entirely different of course...
