Using my QDE 3.0.0 running on windows, I can successfully download to my QNX neutrino v6.3.2 target system (x86).
I can also use the system monitor to view processes etc.
However, if I start my application with /Run/Resume, it terminates with segmentation fault before reaching the main 
function.
If I execute the downloaded application in the command line of the target system, it runs ok.
I have a different target system with the same version, where the QDE debugger works ok.
