Subject: Debugging a NullPointerException in fstack
Date: Tue, 10 Jun 2008 07:20:00 -0000	[thread overview]
Message-ID: <> (raw)


I've compiled frysk on an i386 Fedora 8 system (thanks a lot to Rick  
Moseley for all his previous help on IRC), and I'm attempting to play  
with fstack. It seems to work on some processes (e.g., bash) but goes  
down with a NullPointerException on most others (gconf, gnome- 
screensaver, others).

I was wondering whether this was a known issue and if not, what the  
best way to debug this would be. There is no stack trace displayed, so  
I'm not sure where the NPE is actually coming from. I was wondering if  
it was possible to compile frysk in a way that would make it more  
amenable to being debugged? Also, what is the recommended way to  
debug? gdb, printfs?
