warning causes asdf:load-system to fail

Jim Newton

Can someone help me understand why this fails? I've uploaded a small
testcase to dropbox. https://www.dropbox.com/s/hlnwkbvghegkfkz/debug-12...

I get similar results with and without using slime.
The simple case is that I start sbcl, and call
(asdf:load-system :debug-123)

The code seems to load, and the desired warning message is printed.

But then I get the following errors, which I don't understand.
Can someone help em understand?

Thanks Robert Goldman for pointing me to the issue.
The problem is that if a condition warning condition is raised during compilation, compile-file
is specified to consider this a failure. An exception is made for style-warning conditions.

compile-file --> The tertiary value, failure-p, is false if no conditions of type error or warning (other than style-warning) were detected by the compiler, and true otherwise.

The reason my example was working when I called compile-file directly was simply that I was ignoring the 3rd return value. voila.
