Maybe you can turn this bit on just after NCurses initialisation?

The debugged program is entirely under the control of the terminal 
emulator. I don't know how I can tell it to redirect its standard error 
output to the standard error output of the terminal emulator, or 
(better) a specific pipe, so that the IDE gets the data... It should be 
possible with a named pipe, I will try...
