RE: does GNUstep support exception as well as apple implementation?

[Nicola Pero]

Depending on how your Objective-C environment is setup on Linux, it is possible 
that 
@try/@catch/@throw may not work or not be configured.

In that case, you should use NS_DURING/NS_HANDLER/NS_ENDHANDLER.  The syntax 
and internals
are not slick but they work and have been in use for ages. ;-)

Thanks

Hi folks,

I am studying objc these days.I decide to use GNUstep as development env
since I am familiar with Linux. I use following link as my tutorial.
http://www.otierney.net/objective-c.html.en#exceptions
But I see the example code execution result is different to that article.

The expected result should be:

Cup level is: 10
Cup level is: 20
Cup level is: 30
Cup level is: 40
CupWarningException: Cup level is: 50

CupWarningException: Cup level is: 60
CupWarningException: Cup level is: 70
CupWarningException: Cup level is: 80
CupWarningException: Cup level is: 90
CupWarningException: Cup level is: 100
CupOverflowException: Cup level is: 110

CupUnderflowException: The level is below 0

But my result which compiled with GNUstep is following:

Cup level is: 10
Cup level is: 20
Cup level is: 30
Cup level is: 40
Aborted

Does it mean the exception implementation of GNUstep is not complete as well
as Apple runtime?

Thanks,
Shuduo
