[Bug 260467] New: ddd: backtrace is missing symbols when specifying process pid or core file on command line
https://bugzilla.novell.com/show_bug.cgi?id=260467 Summary: ddd: backtrace is missing symbols when specifying process pid or core file on command line Product: openSUSE 10.3 Version: Alpha 2plus Platform: Other OS/Version: Other Status: NEW Severity: Normal Priority: P5 - None Component: Development AssignedTo: pth@novell.com ReportedBy: rnissl@gmx.de QAContact: qa@suse.de Try something like that: rnissl@video:~> sleep 300 & ddd /bin/sleep $! [1] 23361 In ddd's gdb output window type the commands bt, detach, attach 23361 and bt. The output will look like below. See the difference in the output of the bt command. The same difference exists for supplying a core file on the command line respectively when loading it via ddd's menu file/open core dump. The bt command works like expected already at the first invocation when directly using gdb (i. e. substitute ddd with gdb in the above command), so I think this is an issue of ddd.

I tried to reproduce the bug on 10.2 and 10.3 Alpha1 but there was no problem. I will try it later on 10.3 Alpha4. Maybe you also updated the release. Please, could you test this issue again?

Further investigation shows the following: - move away any existing ~/.ddd directory - start ddd as mentioned above - bt works out of the box - open menu "edit/gdb settings..." - just hit the button labeled "close" - quit ddd - start ddd again as mentioned above - bt doesn't work out of the box anymore! -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.

According to your last description I reproduced the bug. Now I'm going to investigate it. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug, or are watching someone who is.
