Hi,
everytime I stop a debugging session with Live Memory Engine and Live Variables enabled I don’t see the Live Variables in the next debugging session. So I always have to disable the Live Memory Engine prior to stopping the debugging session to have the Live Variables shown in the next session. It seems, that the vgdbsettings.user file won’t be loaded completely when the Live Memory Engine is enabled. I’m on VisualGDB 5.2r4 and have seen this issue in different versions as well. I’m wondering if someone else has seen this behavior?
Best regards
Michael
Hi,
Based on your description, you have set Live Variables to some scope-dependent objects (e.g. static members of a class) without using the full scope (e.g. s_Variable instead of MyClass::s_Variable). Next time you start the debugging session, VisualGDB would evaluate ‘s_Variable’ when the program starts, not find it (because the program is not in the scope of MyClass yet) and consider it deleted. Please try using fully qualified names for your variables to fix this.
If you are not sure, please switch the GDB Session window to All GDB Output mode and check for commands trying to evaluate the variables you added in the previous session. The output from gdb should explain why they fail.
Hi,
thank you for the quick response. The variables are in the global scope in a C project and VisualGDB finds them everytime I start a debugging session, but when in the last debugging session a memory window with live memory was active and the session was stopped and started again the variables are not visible. When I then disable the Live Memory Engine in the memory window, stop the debugging session and start it again the variables become visible again.
Hi,
I made a short video that makes this behavior clear: https://drive.google.com/open?id=0B5WiEZNPXgbET2NfcTJmY29VRFE

[ 9653 ms] =thread-group-exited,id=”i1″Hi,
Thanks for the video, it really helped reproduce the problem. Turns out, it was a race condition between live variables and live memory initialization.
We have fixed it in this build: http://sysprogs.com/files/tmp/VisualGDB-5.2.14.1337.msi
