[Lazarus] Issuing debug commands from the ide.

[Martin]

I was wondering, when I saw the log that you posted on mantis.... I saw 
breakpoints in the debugger code ....

Have you tried to compile the IDE with DBG_WITH_DEBUGGER_DEBUG
  defined?

It does exactly the above. It has been there a very long time.

It has also been decided, that this feature will only be available via 
this define.
Reason: This is mainly for people who wish to debug/experiment with the 
debugger. And it also requires knowledge of both: gdb and how the IDE 
deals with gdb.

If in this command window you execute statements, that run the exe 
("-exec-continue" / "c") then the  IDE looses sync, and your debug 
session is gone. Even if you change the stackframe or thread, you can 
get wrong results....
Fixing all this will only make the ide code more complex and harder to 
maintain.

Not sure of the use of that?
What data do you want to display?
