You used the phrase "error message", but the line that mentions
doesn't look as an error message. That's why I thought you were
talking about the crash message, which does look like error message:
General Protection Fault at eip=000594a5
Anyway, since we are both not native English speakers, it should be no
surprise that this misunderstanding happened. There's no need to be
so upset because of that.

When the chain of memory managed by malloc is corrupted, _any_
function that calls malloc or free can crash. So there's nothing
special about '___cxa_bad_typeid' in your case; that function has
nothing to do with the reasons your program crashes.

We can say something else--that I was trying to help you understand
the _real_ reasons for your crash, and in response got the kind of
nasty attitude that will make me think twice before trying to help
you next time.
