"Unable to restore previously selected frame"

"Unable to restore previously selected frame"

[Phil Edwards]

What does this error mean?  It seems to pop up (literally, in its own
popup box) at seemingly random occasions.  Usually the first time is when
I execute a "p some_variable" in the console window, but after that it
appears according to its own mysterious whims.

I'm using CVS Insight sources.  Do I need to be concerned about this message?

This is a warning that is generated from somewhere in the depths of gdb. 
It is generated when, for some unknown reason, gdb cannot restore the 
target state after an inferior function call. I seldom see them when I am 
not doing inferior function calls or forcing a function return. I would 
not expect to see this message simply from printing the value of a 
variable (unless the variable is in an inferior function call).

I usually just ignore them (but I haven't seen one in ages). YMMV.

You can also ask on the gdb list: maybe they have a better answer.

Could this error be given one of those "never see this again" check
boxes?  (Then insert my diatribe about how this setting should be
saved in .gdbtkinit... :-)

We should be able to come up with a way to do this...

Ah, okay, that explains things.  All is well.  Thanks!
