Hi Richard, Adam,

First, thanks a lot for your answers !

I am currently in big trouble trying to find the cause of a "double free" which occurs when releasing an autorelease pool. Has anybody any idea to know how to identify where an autoreleased objects was freed (released, I guess) before being autoreleases ?

[NSObject+enableDoubleReleaseCheck:] might well help you.

This helped me to see that there is actually a double release check, but I would like the debugger to break on the raising of the "NSGenericException". On OSX, there is the "NSHangOnUncaughtException = YES;" provided by NSDebug, but it does not seem to be on GNUstep :/

Is there any workaround ?

I think you could also try setting the env var


I did not manage to find documentation on this, and it does not seem to have any effect. What is this used for ?
