Simple example:

Code
alias crashtest {
  var %url http://hello:world@example.com
  echo -a urlget sent: $urlget(%url,bg,&reqtestresp,noop)
}

This used to work fine in the past, but at some point it started crashing mIRC.

Still happens in v7.81, I don't know when it started.

As a workaround I can of course pass the authorization header directly, like this:

Code
bset -t &reqtesthdr 1 Authorization:Basic .......

But it's less pleasant since it requires base64 encoding it etc.

In any case, whatever I put in the URL, it should never crash mIRC.
