I found this today.
If you have quite long command line arguments set up in Plato using (Projects>Properties>Miscellaneous>Launch Arguments), the debugger crashes when it is invoked from Plato.
Presumably there is a fixed size buffer allocated for the arguments which is being over-run.
This isn't a big problem, just letting you know. I got around it by using shorter file names for some of my arguments.
