updating the local variables may hang gdb

[ZungBang]

In the program I'm trying to debug there's a local variable which is a class instance with a static member of the same type. This causes gdb to enter an endless loop whenever it is displayed (e.g. with info locals or when generating the response to -stack-list-variables --simple-values), and this causes gdbgui to hang in turn until I send SIGINT to gdb.

I have two suggestions:

• a workaround: make gdbgui only issue the stack-list-variables query when the locals pane is not collapsed. This way I'll still be able to step through the code by hiding the locals.

• a possible fix: use -stack-list-variables --no-values to query the locals and function args and then create a var for each (i.e. start "watching" all locals) - this seems to work when I do it manually... (mmm, you'd probably need to remove all the watched locals and re-add them every time the gui is updated)

I like the second option. It would also make the code I have to maintain a little simpler. I will add it to my TODO list :).
