Re: Serious GORM bug

[Gregory Casamento]

Part of the problem could be with Dragon and drop itself. Try another application which uses Dragon to see if that fans. On some systems there might be a problem with the drag-and-drop daemon.

OK, recompiled current GNUstep from scratch. Still no luck. Now gonna try the most recent release. Wish me luck! :)

Optimization??? I just use configure and the supplied makefile. Anyway, I'm gonna completely wipe out the current GNUstep installation and build it from scratch. I suspect some corruption crept in with that nasty system crash I had. I reinstalled GNUstep on top of the old installation that time. I'll first use the sources I already had and see if the bug goes away. regardless, I'll update after that. Stand by for updates.

I was not able to reproduce your problem on my system. Maybe more
detailed instructions would be helpful. What I noticed when looking at
your stack trace is that a lot of intermediate methods are left out
there. Which optimisation level are you using for your compiler when
compiling GNUstep gui?
You should also try to print out the event (po theEvent and p *theEvent)
and inspect the window given in the event. This should be the window the
event gets send to.

Could you please update your GNUstep installation to the latest release?
This makes it easier to compare the line numbers in the stack trace.
