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?
