Hi Riccardo,
if you look at the line NSProcessInfo.m:1015 you will find:
_NSLog_printf_handler(_GNU_MISSING_MAIN_FUNCTION_CALL);
Now it is definitely a problem that this line leads to a recursion and
somebody with more base knowledge should look into that. Most liekly the
function GSPrivateDefaultsFlag() needs another safety hatch. But the
problem seems not to be related to PikoPixel directly. The only possible
connection that I see is that there user defaults get set from a +load
method (PPGNUstepGlue_ModifierKeys.m). You could comment out the code in
that +load method and see if this changes the behaviour for you.
Hope this helps,
Fred
