I agree with you on both points but I'm talking about really simple programs
here. There isn't any dynamic memory allocation at all.
For example see my previous post
"Exception: STATUS_PRIVILEGED_INSTRUCTION occurs before main is executed."
If you can find a C++ issue with that I'd like to know about it.
Of course that one could be down to needing a magic switch on gcc that I
don't know about.
I'll post an example with the destructor problem shortly and you can debug
it
for me if you like :-). I would love it to be a newbie error that I let
creep
in.
