[oops]

I am writing the "Filesystem demo" on the user mannul.
It compiled well and linked well but resulted in a runtime error.
When I steped over the code, I found a sentence

Ice::Identity myID = Ice::stringToIdentity( parent ? IceUtil::generateUUID() : "RootDir" );

triggered this debug assertion failure .

It seems that this segment of code in <xstring> caused the assertion failure when calling IceUtil::generateUUID().

~basic_string()
{ // destroy the string
_Tidy(true);
}

I don't know what's that.Anyone can help me?

regards
oops
