I got the following exception when trying to build my app:

Because the compiler crashed, it couldn't tell me what line number the error came from. After some guesswork, I figured out the error was caused by an interface that references its own type in a method signature, i.e.:
typedef Foo as interface {
function bar(otherFoo as Foo) as Boolean;
};
Changing the type of otherFoo to object prevents the compiler from crashing.
Unfortunately, I haven't been able to produce a self-contained bit of code that replicates the bug for sharing.
The error happens only for SDK versions 7.1.0+.
